|
||||
|

* AWS EC2 eu-west-1 [c5.large](https://aws.amazon.com/ec2/instance-types/c5/) (2x Xeon Platinum 8124M CPU @ 3.00GHz)
|
||||
* Ubuntu 17.10 (hvm:ebs-ssd, 20180102, ami-0741d47e)
|

* Node.js v8.9.4
|
||||
* Ubuntu 18.04 (hvm-ssd/ubuntu-bionic-18.04-amd64-server-20180912 ami-00035f41c82244dab)

|
||||
|
||||
### The contenders
|
||||
|
||||
* [jimp](https://www.npmjs.com/package/jimp) v0.2.28 - Image processing in pure JavaScript. Bilinear interpolation only.
|
||||
* [pajk-lwip](https://www.npmjs.com/package/pajk-lwip) v0.2.0 (fork) - Wrapper around CImg that compiles dependencies from source.
|
||||
* [mapnik](https://www.npmjs.org/package/mapnik) v3.6.2 - Whilst primarily a map renderer, Mapnik contains bitmap image utilities.
|
||||
* [jimp](https://www.npmjs.com/package/jimp) v0.5.3 - Image processing in pure JavaScript. Provides bicubic interpolation.
|
||||
* [mapnik](https://www.npmjs.org/package/mapnik) v4.0.1 - Whilst primarily a map renderer, Mapnik contains bitmap image utilities.
|
||||
* [imagemagick-native](https://www.npmjs.com/package/imagemagick-native) v1.9.3 - Wrapper around libmagick++, supports Buffers only.
|
||||
* [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) v1.23.1 - Fully featured wrapper around GraphicsMagick's `gm` command line utility.
|
||||
* [images](https://www.npmjs.com/package/images) v3.0.1 - Compiles dependencies from source. Provides bicubic interpolation.
|
||||
* sharp v0.19.0 / libvips v8.6.1 - Caching within libvips disabled to ensure a fair comparison.
|
||||
* sharp v0.21.0 / libvips v8.7.0 - Caching within libvips disabled to ensure a fair comparison.
