Benchmarks
For reference, several fast compression algorithms were tested and compared on a server running Arch Linux (Linux version 5.5.11-arch1-1), with a Core i9-9900K CPU @ 5.0GHz, using lzbench, an open-source in-memory benchmark by @inikep compiled with gcc 9.3.0, on the Silesia compression corpus.
