Here is an updated chart - and the data (2019): https://community.centminmod.com/threads/round-4-compression-comparison-benchmarks-zstd-vs-brotli-vs-pigz-vs-bzip2-vs-xz-etc.18669/ https://community.centminmod.com/threads/round-4-compression... Yes, though decompression speed (+memory to some extent) should also be considered. Also different input types has different characteristics, so a single type isn't very representative. While ultimate compression efficiency is interesting, in practice I find that most often you are looking for a "good enough", meaning "give me the best at xxxMB/s". For most purposes (de)compression at 50MB/s is just too slow to bother. For a server anything considerably below 1GB/s/core is too slow, otherwise you will too easily saturate your CPU before your NIC or disks are saturated.
