## Benchmarks
For reference, several fast compression algorithms were tested and compared
on a server running Linux Debian (`Linux version 4.14.0-3-amd64`),
with a Core i7-6700K CPU @ 4.0GHz,
on a server running Arch Linux (`Linux version 5.0.5-arch1-1`),
with a Core i9-9900K CPU @ 5.0GHz,
using [lzbench], an open-source in-memory benchmark by @inikep
compiled with [gcc] 7.3.0,
compiled with [gcc] 8.2.1,
on the [Silesia compression corpus].
