 ### Test environment
 
 * AWS EC2 [c4.xlarge](http://aws.amazon.com/ec2/instance-types/#c4) (4x E5-2666 v3 @ 2.90GHz)
-* Amazon Linux AMI 2016.03.1 (HVM), SSD Volume Type
-* Node.js v6.2.0
+* Ubuntu 16.04.1 LTS (HVM, SSD)
+* Node.js v6.9.1
 
 ### The contenders
 
-* [jimp](https://www.npmjs.com/package/jimp) v0.2.24 - Image processing in pure JavaScript. Bilinear interpolation only.
-* [lwip](https://www.npmjs.com/package/lwip) v0.0.9 - Wrapper around CImg, compiles dependencies from source.
-* [imagemagick-native](https://www.npmjs.com/package/imagemagick-native) v1.9.2 - Wrapper around libmagick++, supports Buffers only.
+* [jimp](https://www.npmjs.com/package/jimp) v0.2.27 - Image processing in pure JavaScript. Bilinear interpolation only.
+* [lwip](https://www.npmjs.com/package/lwip) v0.0.9 - Wrapper around CImg. Compiles outdated, insecure dependencies from source.
+* [mapnik](https://www.npmjs.org/package/mapnik) v3.5.14 - 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) v1.22.0 - Fully featured wrapper around GraphicsMagick's `gm` command line utility.
-* sharp v0.15.0 / libvips v8.3.1 - Caching within libvips disabled to ensure a fair comparison.
+* [gm](https://www.npmjs.com/package/gm) v1.23.0 - Fully featured wrapper around GraphicsMagick's `gm` command line utility.
+* sharp v0.17.0 / libvips v8.4.2 - Caching within libvips disabled to ensure a fair comparison.
 
 ### The task
 
 Decompress a 2725x2225 JPEG image,
 resize to 720x480 using Lanczos 3 resampling (where available),
-then compress to JPEG.
+then compress to JPEG at a "quality" setting of 80.

 Greater libvips performance can be expected with caching enabled (default)
 and using 8+ core machines, especially those with larger L1/L2 CPU caches.
