 ### Test environment
 
-* AWS EC2 [c3.xlarge](http://aws.amazon.com/ec2/instance-types/#Compute_Optimized)
-* Ubuntu 14.04
-* libvips 7.40.8
+* AWS EC2 [c4.xlarge](http://aws.amazon.com/ec2/instance-types/#c4)
+* Ubuntu 15.04
+* Node.js 0.12.7
+* libvips 8.0.2
 * liborc 0.4.22
 
 ### The contenders
 
-* [imagemagick-native](https://github.com/mash/node-imagemagick-native) v1.2.2 - Supports Buffers only
-* [imagemagick](https://github.com/yourdeveloper/node-imagemagick) v0.1.3 - Supports filesystem only and "has been unmaintained for a long time".
-* [gm](https://github.com/aheckmann/gm) v1.16.0 - Fully featured wrapper around GraphicsMagick.
-* sharp v0.6.2 - Caching within libvips disabled to ensure a fair comparison.
+* [lwip](https://www.npmjs.com/package/lwip) 0.0.7 - Wrapper around CImg, compiles dependencies from source
+* [imagemagick-native](https://www.npmjs.com/package/imagemagick-native) git@45d4e2e - Supports Buffers only
+* [imagemagick](https://www.npmjs.com/package/imagemagick) 0.1.3 - Supports filesystem only and "has been unmaintained for a long time".
