That seems different than other results I've seen. According to the
wikipedia page (
https://en.wikipedia.org/wiki/Zstandard) and the
references therein, Ubuntu found that zstd level 19 was faster but with
poorer compression when compared with xz level 2 (which is the same
level that we use now).
If the smallest size is the goal, wouldn't it be worth trying to just use a
higher xz level instead?
