6	zstd:11	29	188	3204558848	0.5511	64.599	Compression was enabled using the `compress-force=` mount option
7	zstd:10	24	229	3205373952	0.5512	53.478	Speed and time was measured with `pv`
8	zstd:9	20	274	3206897664	0.5515	44.591	Compressed size was masured with `compsize -b`
9	zstd:8	17	311	3209912320	0.5520	37.946	Reduction = 1 - Ratio
10	zstd:7	15	361	3212718080	0.5525	33.518	Resulting compressed size seems to be somewhat varbiable, you will not get the exact same results!
11	zstd:6	13	410	3222077440	0.5541	29.154	Rates > 1GiB/s were originally in GiB/s rounded to 2 decimal places by `pv` and then converted to MiB/s by me
