-### Does this problem relate to file caching?
-
-The default behaviour of libvips is to cache input files, which can lead to `EBUSY` or `EPERM` errors on Windows.
-Use [`sharp.cache(false)`](https://sharp.pixelplumbing.com/api-utility#cache) to switch this feature off.
-
-- [ ] Adding `sharp.cache(false)` does not fix this problem.
-
-### Does this problem relate to images appearing to have been rotated by 90 degrees?
-
-Images that contain EXIF Orientation metadata are not auto-oriented. By default, EXIF metadata is removed.
-
-- To auto-orient pixel values use the parameter-less [`rotate()`](https://sharp.pixelplumbing.com/api-operation#rotate) operation.
-- To retain EXIF Orientation use [`keepExif()`](https://sharp.pixelplumbing.com/api-output#keepexif).
-
-- [ ] Using `rotate()` or `keepExif()` does not fix this problem.

+# Installation
+
+```sh
+npm install sharp
+```
+
+```sh
+yarn add sharp
+```
+
+## Prerequisites
+
+* Node.js >= 14.15.0
+
+## Prebuilt binaries
+
+Ready-compiled sharp and libvips binaries are provided for use on the most common platforms:
+
+* macOS x64 (>= 10.13)
+* macOS ARM64
+* Linux x64 (glibc >= 2.17, musl >= 1.1.24, CPU with SSE4.2)
+* Linux ARM64 (glibc >= 2.17, musl >= 1.1.24)
+* Windows x64
+* Windows x86
+
+A ~7MB tarball containing libvips and its most commonly used dependencies
+is downloaded via HTTPS, verified via Subresource Integrity
+and decompressed into `node_modules/sharp/vendor` during `npm install`.
+
+This provides support for the
+JPEG, PNG, WebP, AVIF (limited to 8-bit depth), TIFF, GIF and SVG (input) image formats.
+
+The following platforms have prebuilt libvips but not sharp:
+
+* Linux ARMv7 (glibc >= 2.28)
+* Linux ARMv6 (glibc >= 2.28)
+* Windows ARM64
+
+The following platforms require compilation of both libvips and sharp from source:
+
+* Linux x86
+* Linux ARMv7 (glibc <= 2.27, musl)
+* Linux ARMv6 (glibc <= 2.27, musl)
+* Linux PowerPC
+* FreeBSD
+* OpenBSD
+
+## Common problems
+
+The architecture and platform of Node.js used for `npm install`
+must be the same as the architecture and platform of Node.js used at runtime.
+See the [cross-platform](#cross-platform) section if this is not the case.
+
+When using npm v6 or earlier, the `npm install --unsafe-perm` flag must be used when installing as `root` or a `sudo` user.
+
+When using npm v7 or later, the user running `npm install` must own the directory it is run in.
+
+The `npm install --ignore-scripts=false` flag must be used when `npm` has been configured to ignore installation scripts.
+
+Check the output of running `npm install --verbose --foreground-scripts sharp` for useful error messages.
+
+## Apple M1
+
+Prebuilt sharp and libvips binaries have been provided for macOS on ARM64 since sharp v0.29.0.
+
+## Cross-platform
+
+At `npm install` time, prebuilt binaries are automatically selected for the
+current OS platform and CPU architecture, where available.
+
+The target platform and/or architecture can be manually selected using the following flags.
+
+```sh
+npm install --platform=... --arch=... --arm-version=... sharp
+```
+
+* `--platform`: one of `linux`, `darwin` or `win32`.
+* `--arch`: one of `x64`, `ia32`, `arm` or `arm64`.
+* `--arm-version`: one of `6`, `7` or `8` (`arm` defaults to `6`, `arm64` defaults to `8`).
+* `--libc`: one of `glibc` or `musl`. This option only works with platform `linux`, defaults to `glibc`
+* `--sharp-install-force`: skip version compatibility and Subresource Integrity checks.
+
+These values can also be set via environment variables,
+`npm_config_platform`, `npm_config_arch`, `npm_config_arm_version`, `npm_config_libc`
+and `SHARP_INSTALL_FORCE` respectively.
+
+For example, if the target machine has a 64-bit ARM CPU and is running Alpine Linux,
+use the following flags:
+
+```sh
+npm install --arch=arm64 --platform=linux --libc=musl sharp
+```
+
+If the current machine is Alpine Linux and the target machine is Debian Linux on x64 cpu,
+use the following flags:
+
+```sh
+npm install --arch=x64 --platform=linux --libc=glibc sharp
+```
+
+Multiple platforms and architectures can be supported within the same installation tree.
+The following example for macOS installs x64 binaries then adds (via a rebuild) arm64 binaries:
+
+```sh
+npm install --platform=darwin --arch=x64 sharp
+npm rebuild --platform=darwin --arch=arm64 sharp
+```
+
+## Custom libvips
+
+To use a custom, globally-installed version of libvips instead of the provided binaries,
+make sure it is at least the version listed under `config.libvips` in the `package.json` file
+and that it can be located using `pkg-config --modversion vips-cpp`.
+
+For help compiling libvips and its dependencies, please see
+[building libvips from source](https://www.libvips.org/install.html#building-libvips-from-source).
+
+The use of a globally-installed libvips is unsupported on Windows
+and on macOS when running Node.js under Rosetta.
+
+## Building from source
+
+This module will be compiled from source at `npm install` time when:
+
+* a globally-installed libvips is detected (set the `SHARP_IGNORE_GLOBAL_LIBVIPS` environment variable to skip this),
+* prebuilt sharp binaries do not exist for the current platform, or
+* when the `npm install --build-from-source` flag is used.
+
+Building from source requires:
+
+* C++11 compiler
+* [node-gyp](https://github.com/nodejs/node-gyp#installation) and its dependencies
+
+## Custom prebuilt binaries
+
+This is an advanced approach that most people will not require.
+
+### Prebuilt sharp binaries
+
+To install the prebuilt sharp binaries from a custom URL,
+set the `sharp_binary_host` npm config option
+or the `npm_config_sharp_binary_host` environment variable.
+
+To install the prebuilt sharp binaries from a directory on the local filesystem,
+set the `sharp_local_prebuilds` npm config option
+or the `npm_config_sharp_local_prebuilds` environment variable.
+
+URL example:
+if `sharp_binary_host` is set to `https://hostname/path`
+and the sharp version is `1.2.3` then the resultant URL will be
+`https://hostname/path/v1.2.3/sharp-v1.2.3-napi-v5-platform-arch.tar.gz`.
+
+Filename example:
+if `sharp_local_prebuilds` is set to `/path`
+and the sharp version is `1.2.3` then the resultant filename will be
+`/path/sharp-v1.2.3-napi-v5-platform-arch.tar.gz`.
+
+### Prebuilt libvips binaries
+
+To install the prebuilt libvips binaries from a custom URL,
+set the `sharp_libvips_binary_host` npm config option
+or the `npm_config_sharp_libvips_binary_host` environment variable.
+
+To install the prebuilt libvips binaries from a directory on the local filesystem,
+set the `sharp_libvips_local_prebuilds` npm config option
+or the `npm_config_sharp_libvips_local_prebuilds` environment variable.
+
+The version subpath and filename are appended to these.
+
+URL example:
+if `sharp_libvips_binary_host` is set to `https://hostname/path`
+and the libvips version is `4.5.6` then the resultant URL will be
+`https://hostname/path/v4.5.6/libvips-4.5.6-platform-arch.tar.br`.
+
+Filename example:
+if `sharp_libvips_local_prebuilds` is set to `/path`
+and the libvips version is `4.5.6` then the resultant filename will be
+`/path/v4.5.6/libvips-4.5.6-platform-arch.tar.br`.
+
+See the Chinese mirror below for a further example.
+
+If these binaries are modified, new integrity hashes can be provided
+at install time via `npm_package_config_integrity_platform_arch`
+environment variables, for example set
+`npm_package_config_integrity_linux_x64` to `sha512-abc...`.
+
+The integrity hash of a file can be generated via:
+```sh
+sha512sum libvips-x.y.z-platform-arch.tar.br | cut -f1 -d' ' | xxd -r -p | base64 -w 0
+```
+
+## Chinese mirror
+
+A mirror site based in China, provided by Alibaba, contains binaries for both sharp and libvips.
+
+To use this either set the following configuration:
+
+```sh
+npm config set sharp_binary_host "https://npmmirror.com/mirrors/sharp"
+npm config set sharp_libvips_binary_host "https://npmmirror.com/mirrors/sharp-libvips"
+npm install sharp
+```
+
+or set the following environment variables:
+
+```sh
+npm_config_sharp_binary_host="https://npmmirror.com/mirrors/sharp" \
+  npm_config_sharp_libvips_binary_host="https://npmmirror.com/mirrors/sharp-libvips" \
+  npm install sharp
+```
+
+## FreeBSD
+
+The `vips` package must be installed before `npm install` is run.
+
+```sh
+pkg install -y pkgconf vips
+```
+
+```sh
+cd /usr/ports/graphics/vips/ && make install clean
+```
+
+## Linux memory allocator
+
+The default memory allocator on most glibc-based Linux systems
+(e.g. Debian, Red Hat) is unsuitable for long-running, multi-threaded
+processes that involve lots of small memory allocations.
+
+For this reason, by default, sharp will limit the use of thread-based
+[concurrency](api-utility#concurrency) when the glibc allocator is
+detected at runtime.
+
+To help avoid fragmentation and improve performance on these systems,
+the use of an alternative memory allocator such as
+[jemalloc](https://github.com/jemalloc/jemalloc) is recommended.
+
+Those using musl-based Linux (e.g. Alpine) and non-Linux systems are
+unaffected.
+
+## AWS Lambda
+
+The `node_modules` directory of the
+[deployment package](https://docs.aws.amazon.com/lambda/latest/dg/nodejs-package.html)
+must include binaries for the Linux x64 platform.
+
+When building your deployment package on machines other than Linux x64 (glibc),
+run the following additional command after `npm install`:
+
+```sh
+npm install
+rm -rf node_modules/sharp
+SHARP_IGNORE_GLOBAL_LIBVIPS=1 npm install --arch=x64 --platform=linux --libc=glibc sharp
+```
+
+To get the best performance select the largest memory available.
+A 1536 MB function provides ~12x more CPU time than a 128 MB function.
+
+When integrating with AWS API Gateway, ensure it is configured with the relevant
+[binary media types](https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-payload-encodings.html).
+
+## Bundlers
+
+### webpack
+
+Ensure sharp is excluded from bundling via the
+[externals](https://webpack.js.org/configuration/externals/)
+configuration.
+
+```js
+externals: {
+  'sharp': 'commonjs sharp'
+}
+```
+
+### esbuild
+
+Ensure sharp is excluded from bundling via the
+[external](https://esbuild.github.io/api/#external)
+configuration.
+
+```js
+buildSync({
+  entryPoints: ['app.js'],
+  bundle: true,
+  platform: 'node',
+  external: ['sharp'],
+})
+```
+
+```sh
+esbuild app.js --bundle --platform=node --external:sharp
+```
+
+For `serverless-esbuild`, ensure platform-specific binaries are installed
+via the `serverless.yml` configuration.
+
+```yaml
+custom:
+  esbuild:
+    external:
+      - sharp
+    packagerOptions:
+      scripts:
+        - npm install --arch=x64 --platform=linux sharp
+```
+
+## TypeScript
+
+TypeScript definitions are published as part of
+the `sharp` package from v0.32.0.
+
+Previously these were available via the `@types/sharp` package,
+which is now deprecated.
+
+When using Typescript, please ensure `devDependencies` includes
+the `@types/node` package.
+
+## Fonts
+
+When creating text images or rendering SVG images that contain text elements,
+`fontconfig` is used to find the relevant fonts.
+
+On Windows and macOS systems, all system fonts are available for use.
+
+On macOS systems using Homebrew, you may need to set the
+`PANGOCAIRO_BACKEND` environment variable to a value of `fontconfig`
+to ensure it is used for font discovery instead of Core Text.
+
+On Linux systems, fonts that include the relevant
+[`fontconfig` configuration](https://www.freedesktop.org/software/fontconfig/fontconfig-user.html)
+when installed via package manager are available for use.
+
+If `fontconfig` configuration is not found, the following error will occur:
+```
+Fontconfig error: Cannot load default config file
+```
+
+In serverless environments where there is no control over font packages,
+use the `FONTCONFIG_PATH` environment variable to point to a custom location.
+
+Embedded SVG fonts are unsupported.
+
+## Worker threads
+
+On some platforms, including glibc-based Linux,
+the main thread must call `require('sharp')`
+_before_ worker threads are created.
+This is to ensure shared libraries remain loaded in memory
+until after all threads are complete.
+
+Without this, the following error may occur:
+```
+Module did not self-register
+```
+
+## Known conflicts
+
+### Canvas and Windows
+
+The prebuilt binaries provided by `canvas` for Windows
+from v2.7.0 onwards depend on the Visual C++ Runtime (MSVCRT).
+These conflict with the binaries provided by sharp,
+which depend on the more modern Universal C Runtime (UCRT).
+
+See [Automattic/node-canvas#2155](https://github.com/Automattic/node-canvas/issues/2155).
+
+If both modules are used in the same Windows process, the following error will occur:
+```
+The specified procedure could not be found.
+```

+# Performance
+
+A test to benchmark the performance of this module relative to alternatives.
+
+Greater libvips performance can be expected with caching enabled (default)
+and using 8+ core machines, especially those with larger L1/L2 CPU caches.
+
+The I/O limits of the relevant (de)compression library will generally determine maximum throughput.
+

----
-title: Installation
----
-
-Works with your choice of JavaScript package manager.
-
-:::caution
-Please ensure your package manager is configured to install optional dependencies
-:::
-
-If a package manager lockfile must support multiple platforms,
-please see the [cross-platform](#cross-platform) section
-to help decide which package manager is appropriate.
-
-```sh
-npm install sharp
-```
-
-```sh
-pnpm add sharp
-```
-
-When using `pnpm`, you may need to add `sharp` to
-[ignoredBuiltDependencies](https://pnpm.io/settings#ignoredbuiltdependencies)
-to silence warnings.
-
-```sh
-yarn add sharp
-```
-
-```sh
-bun add sharp
-```
-
-```sh
-deno run --allow-ffi ...
-```
-
-## Prerequisites
-
-* Node-API v9 compatible runtime e.g. Node.js ^18.17.0 or >=20.3.0.
-
-## Prebuilt binaries
-
-Ready-compiled sharp and libvips binaries are provided for use on the most common platforms:
-
-* macOS x64 (>= 10.15)
-* macOS ARM64
-* Linux ARM (glibc >= 2.31)
-* Linux ARM64 (glibc >= 2.26, musl >= 1.2.2)
-* Linux ppc64 (glibc >= 2.31)
-* Linux s390x (glibc >= 2.31)
-* Linux x64 (glibc >= 2.26, musl >= 1.2.2, CPU with SSE4.2)
-* Windows x64
-* Windows x86
-* Windows ARM64 (experimental, CPU with ARMv8.4 required for all features)
-
-This provides support for the
-JPEG, PNG, WebP, AVIF (limited to 8-bit depth), TIFF, GIF and SVG (input) image formats.
-
-## Cross-platform
-
-At install time, package managers will automatically select prebuilt binaries
-for the current OS platform and CPU architecture, where available.
-
-Some package managers support multiple platforms and architectures
-within the same installation tree and/or using the same lockfile.
-
-### npm v10+
-
-:::caution
-npm `package-lock.json` files shared by multiple platforms can cause installation problems due to [npm bug #4828](https://github.com/npm/cli/issues/4828)
-:::
-
-Provides limited support via `--os`, `--cpu` and `--libc` flags.
-
-To support macOS with Intel x64 and ARM64 CPUs:
-```sh
-npm install --cpu=x64 --os=darwin sharp
-npm install --cpu=arm64 --os=darwin sharp
-```
-
-When the cross-target is Linux, the C standard library must be specified.
-
-To support glibc (e.g. Debian) and musl (e.g. Alpine) Linux with Intel x64 CPUs:
-```sh
-npm install --cpu=x64 --os=linux --libc=glibc sharp
-npm install --cpu=x64 --os=linux --libc=musl sharp
-```
-
-### yarn v3+
-
-Use the [supportedArchitectures](https://yarnpkg.com/configuration/yarnrc#supportedArchitectures) configuration.
-
-### pnpm v8+
-
-Use the [supportedArchitectures](https://pnpm.io/settings#supportedarchitectures) configuration.
-
-## Custom libvips
-
-To use a custom, globally-installed version of libvips instead of the provided binaries,
-make sure it is at least the version listed under `config.libvips` in the `package.json` file
-and that it can be located using `pkg-config --modversion vips-cpp`.
-
-For help compiling libvips and its dependencies, please see
-[building libvips from source](https://www.libvips.org/install.html#building-libvips-from-source).
-
-The use of a globally-installed libvips is unsupported on Windows
-and on macOS when running Node.js under Rosetta.
-
-## Building from source
-
-This module will be compiled from source at `npm install` time when:
-
-* a globally-installed libvips is detected, or
-* when the `npm install --build-from-source` flag is used.
-
-The logic to detect a globally-installed libvips can be skipped by setting the
-`SHARP_IGNORE_GLOBAL_LIBVIPS` (never try to use it) or
-`SHARP_FORCE_GLOBAL_LIBVIPS` (always try to use it, even when missing or outdated)
-environment variables.
-
-Building from source requires:
-
-* C++17 compiler
-* [node-addon-api](https://www.npmjs.com/package/node-addon-api) version 7+
-* [node-gyp](https://github.com/nodejs/node-gyp#installation) version 9+ and its dependencies
-
-There is an install-time check for these dependencies.
-If `node-addon-api` or `node-gyp` cannot be found, try adding them via:
-
-```sh
-npm install --save node-addon-api node-gyp
-```
-
-When using `pnpm`, you may need to add `sharp` to
-[onlyBuiltDependencies](https://pnpm.io/settings#onlybuiltdependencies)
-to ensure the installation script can be run.
-
-For cross-compiling, the `--platform`, `--arch` and `--libc` npm flags
-(or the `npm_config_platform`, `npm_config_arch` and `npm_config_libc` environment variables)
-can be used to configure the target environment.
-
-## WebAssembly
-
-Experimental support is provided for runtime environments that provide
-multi-threaded Wasm via Workers.
-
-Use in web browsers is unsupported.
-
-Native text rendering is unsupported.
-
-[Tile-based output](/api-output#tile) is unsupported.
-
-```sh
-npm install --cpu=wasm32 sharp
-```
-
-## FreeBSD
-
-The `vips` package must be installed before `npm install` is run.
-
-```sh
-pkg install -y pkgconf vips
-```
-
-```sh
-cd /usr/ports/graphics/vips/ && make install clean
-```
-
-## Linux memory allocator
-
-The default memory allocator on most glibc-based Linux systems
-(e.g. Debian, Red Hat) is unsuitable for long-running, multi-threaded
-processes that involve lots of small memory allocations.
-
-For this reason, by default, sharp will limit the use of thread-based
-[concurrency](/api-utility#concurrency) when the glibc allocator is
-detected at runtime.
-
-To help avoid fragmentation and improve performance on these systems,
-the use of an alternative memory allocator such as
-[jemalloc](https://github.com/jemalloc/jemalloc) is recommended.
-
-Those using musl-based Linux (e.g. Alpine) and non-Linux systems are
-unaffected.
-
-## AWS Lambda
-
-The `node_modules` directory of the
-[deployment package](https://docs.aws.amazon.com/lambda/latest/dg/nodejs-package.html)
-must include binaries for either the linux-x64 or linux-arm64 platforms
-depending on the chosen architecture.
-
-When building your deployment package on a machine that differs from the target architecture,
-see the [cross-platform](#cross-platform) section to help decide which package manager is appropriate
-and how to configure it.
-
-Some package managers use symbolic links
-but AWS Lambda does not support these within deployment packages.
-
-To get the best performance select the largest memory available.
-A 1536 MB function provides ~12x more CPU time than a 128 MB function.
-
-When integrating with AWS API Gateway, ensure it is configured with the relevant
-[binary media types](https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-payload-encodings.html).
-
-## Bundlers
-
-### webpack
-
-Ensure sharp is excluded from bundling via the
-[externals](https://webpack.js.org/configuration/externals/)
-configuration.
-
-```js
-externals: {
-  'sharp': 'commonjs sharp'
-}
-```
-
-### esbuild
-
-Ensure sharp is excluded from bundling via the
-[external](https://esbuild.github.io/api/#external)
-configuration.
-
-```js
-buildSync({
-  entryPoints: ['app.js'],
-  bundle: true,
-  platform: 'node',
-  external: ['sharp'],
-})
-```
-
-```sh
-esbuild app.js --bundle --platform=node --external:sharp
-```
-
-For `serverless-esbuild`, ensure platform-specific binaries are installed
-via the `serverless.yml` configuration.
-
-```yaml
-custom:
-  esbuild:
-    external:
-      - sharp
-    packagerOptions:
-      scripts:
-        - npm install --os=linux --cpu=x64 sharp
-```
-
-### electron
-
-#### electron-builder
-
-Ensure `sharp` is unpacked from the ASAR archive file using the
-[asarUnpack](https://www.electron.build/app-builder-lib.interface.platformspecificbuildoptions#asarunpack)
-option.
-
-```json
-{
-  "build": {
-    "asar": true,
-    "asarUnpack": [
-      "**/node_modules/sharp/**/*",
-      "**/node_modules/@img/**/*"
-    ]
-  }
-}
-```
-
-#### electron-forge
-
-Ensure `sharp` is unpacked from the ASAR archive file using the
-[unpack](https://js.electronforge.io/interfaces/_electron_forge_maker_squirrel.InternalOptions.Options.html#asar)
-option.
-
-```json
-{
-  "packagerConfig": {
-    "asar": {
-      "unpack": "**/node_modules/{sharp,@img}/**/*"
-    }
-  }
-}
-```
-
-When using `electron-forge` with [Webpack](#webpack),
-you may also need to add
-[forge-externals-plugin](https://www.npmjs.com/package/@timfish/forge-externals-plugin).
-
-### vite
-
-Ensure `sharp` is excluded from bundling via the
-[build.rollupOptions](https://vitejs.dev/config/build-options.html)
-configuration.
-
-```js
-import { defineConfig } from 'vite';
-
-export default defineConfig({
-  build: {
-    rollupOptions: {
-      external: [
-        "sharp"
-      ]
-    }
-  }
-});
-```
-
-## TypeScript
-
-TypeScript definitions are published as part of
-the `sharp` package from v0.32.0.
-
-Previously these were available via the `@types/sharp` package,
-which is now deprecated.
-
-When using Typescript, please ensure `devDependencies` includes
-the `@types/node` package.
-
-## Fonts
-
-When creating text images or rendering SVG images that contain text elements,
-`fontconfig` is used to find the relevant fonts.
-
-On Windows and macOS systems, all system fonts are available for use.
-
-On macOS systems using Homebrew, you may need to set the
-`PANGOCAIRO_BACKEND` environment variable to a value of `fontconfig`
-to ensure it is used for font discovery instead of Core Text.
-
-On Linux systems, fonts that include the relevant
-[`fontconfig` configuration](https://www.freedesktop.org/software/fontconfig/fontconfig-user.html)
-when installed via package manager are available for use.
-
-If `fontconfig` configuration is not found, the following error will occur:
-```
-Fontconfig error: Cannot load default config file
-```
-
-In serverless environments where there is no control over font packages,
-use the `FONTCONFIG_PATH` environment variable to point to a custom location.
-
-Embedded SVG fonts are unsupported.
-
-## Known conflicts
-
-### Canvas and Windows

-title: Performance

-
-## Parallelism and concurrency
-
-Node.js uses a libuv-managed thread pool when processing asynchronous calls to native modules such as sharp.
-
-The maximum number of images that sharp can process in parallel is controlled by libuv's
-[`UV_THREADPOOL_SIZE`](https://nodejs.org/api/cli.html#uv_threadpool_sizesize)
-environment variable, which defaults to 4.
-
-When using more than 4 physical CPU cores, set this environment variable
-before the Node.js process starts to increase the thread pool size.
-
-```sh
-export UV_THREADPOOL_SIZE="$(lscpu -p | egrep -v "^#" | sort -u -t, -k 2,4 | wc -l)"
-```
-
-libvips uses a glib-managed thread pool to avoid the overhead of spawning new threads.
-
-The default number of threads used to concurrently process each image is the same as the number of CPU cores,
-except when using glibc-based Linux without jemalloc, where the default is `1` to help reduce memory fragmentation.
-
-Use [`sharp.concurrency()`](/api-utility/#concurrency) to manage the number of threads per image.
-
-To reduce memory fragmentation when using the default Linux glibc memory allocator, set the
-[`MALLOC_ARENA_MAX`](https://www.gnu.org/software/libc/manual/html_node/Memory-Allocation-Tunables.html)
-environment variable before the Node.js process starts to reduce the number of memory pools.
-
-```sh
-export MALLOC_ARENA_MAX="2"
-```
-
-## Benchmark
-
-A test to benchmark the performance of this module relative to alternatives.
-
-Greater libvips performance can be expected with caching enabled (default)
-and using 8+ core machines, especially those with larger L1/L2 CPU caches.
-
-The I/O limits of the relevant (de)compression library will generally determine maximum throughput.
-
-### Contenders
-
-- [jimp](https://www.npmjs.com/package/jimp) v1.6.0 - Image processing in pure JavaScript.
-- [imagemagick](https://www.npmjs.com/package/imagemagick) v0.1.3 - Supports filesystem only and "_has been unmaintained for a long time_".
-- [gm](https://www.npmjs.com/package/gm) v1.25.1 - Fully featured wrapper around GraphicsMagick's `gm` command line utility, but "_has been sunset_".
-- sharp v0.34.3 / libvips v8.17.0 - Caching within libvips disabled to ensure a fair comparison.

-### Task: JPEG
-
-Decompress a 2725x2225 JPEG image,
-resize to 720x588 using Lanczos 3 resampling (where available),
-then compress to JPEG at a "quality" setting of 80.
-
-Note: jimp does not support Lanczos 3, bicubic resampling used instead.
-
-#### Results: JPEG (AMD64)

-### Task: PNG
-
-Decompress a 2048x1536 RGBA PNG image,
-premultiply the alpha channel,
-resize to 720x540 using Lanczos 3 resampling (where available),
-unpremultiply then compress as PNG with a "default" zlib compression level of 6
-and without adaptive filtering.
