Experimenting with mozjpeg 2.0

CloudFlare recently updated its Polish service, which recompresses images to ensure fast delivery to web browsers. The new version uses mozjpeg 2.0 for JPEG compression and outperforms libjpeg-turbo in terms of compression ratio and the number of files compressed. However, it takes longer to compress images. CloudFlare is optimizing mozjpeg 2.0 for Intel processors and will contribute improvements back to the project. The company is also investing in other optimization projects like gzip and LuaJIT.
