### Test environment
* 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
* Amazon Linux AMI 2015.09
* Node.js v4.1.2
### The contenders
* [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 - Wrapper around libmagick++, supports Buffers only.
* [imagemagick](https://www.npmjs.com/package/imagemagick) 0.1.3 - Supports filesystem only and "*has been unmaintained for a long time*".
* [gm](https://www.npmjs.com/package/gm) 1.18.1 - Fully featured wrapper around GraphicsMagick's `convert` command line utility.
* sharp 0.11.0 - Caching within libvips disabled to ensure a fair comparison.
* [jimp](https://www.npmjs.com/package/jimp) v0.2.8 - Image processing in pure JavaScript.
* [lwip](https://www.npmjs.com/package/lwip) v0.0.8 - Wrapper around CImg, compiles dependencies from source.
* ~~[imagemagick-native](https://www.npmjs.com/package/imagemagick-native)~~ - Wrapper around libmagick++, supports Buffers only. Does not currently work with Node.js v4.
* [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) v1.20.0 - Fully featured wrapper around GraphicsMagick's `convert` command line utility.
* sharp v0.11.3 / libvips v8.1.0 - Caching within libvips disabled to ensure a fair comparison.
