Compression levels sorted by compression ratio can be ordered like 19, 20, 21, 22, 18, 17, 16, 15, 14, 13, 8, 9, 10, 11, 12, 6, 7, 5, 0, 3, 4, 2, 1 with some files... Use benchmarks.

Compression levels sorted by decompression speeds can be ordered like 1, 2, 10, 11, 12, 8, 9, 14 with some files and hardware... Use benchmarks.

Compression levels sorted by compression speed can be ordered like 1, 2, 3, 0, 4, 5, ..., 10, 14, 15, 13 with some files and hardware... Use benchmarks.

Use this command in order to get quite accurate benchmarks for your hardware and files: zstd --ultra -b0 -e22 singlefile

zstd 1.5.2 will overrate speeds but just slightly because it will only select the best results...
