GZIP Compression can reduce the size of a website by more than 50%, thus making it much faster to download over the internet. Compression is automatically enabled, and handled correctly by the hosting stack.
Head of R&D at Servebolt, Hans Kristian Rosbach, develops and maintains a modern version of zlib, the compression library that is used for gzip compression. Zlib-ng (Zlib “Next Generation”) compresses both faster, and better than stock versions of zlib. Zlib-ng is in use for all websites hosted on Servebolt.
