-# 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.
-
-## Contenders
-
-* [jimp](https://www.npmjs.com/package/jimp) v0.22.10 - 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) v1.25.0 - Fully featured wrapper around GraphicsMagick's `gm` command line utility.
-* [@squoosh/lib](https://www.npmjs.com/package/@squoosh/lib) v0.5.3 - Image libraries transpiled to WebAssembly, includes GPLv3 code, but "*Project no longer maintained*".
-* [@squoosh/cli](https://www.npmjs.com/package/@squoosh/cli) v0.7.3 - Command line wrapper around `@squoosh/lib`, avoids GPLv3 by spawning process, but "*Project no longer maintained*".
-* sharp v0.33.0 / libvips v8.15.0 - 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.
-

+## 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.
+
+Note: jimp does not support premultiply/unpremultiply.
