Zstd is multi-thread safe, as far as I know, xz is not. But the kernel does
not support zstd.

It has, because lzop is the only algorithm that produces unreproducible builds
due to them adding their own timestamp, which there's no flag to remove. Of course
lzop will be faster than xz, but mkinitcpio's default is gz, which should be comparable,
at least in speed, with lzop.
