My conclusions:
Use lzturbo32 for fast comp, use zpaq3 for slower but better comp.
Annotations:
Everything was done in parallel so depending on the implementation results may differ.
The binaries I used are all in pacman except the brotli one I got it from here: https://github.com/mcmilk/zstdmt
Also on the wiki file zpaq 3 was faster than zpaq 2 which makes no sense to me but ok
CR/CT = compression ratio / compression time * 100
