I've tried zstd on an AMD Athlon II X4 635 (2010): it's perfectly
smooth, can't notice any performance drop.  In fact, I wonder if it's
not even faster than before, but it's hard to measure.

Note that Arch Wiki tends to be on the conservative side when it comes
to performance.  I would not use it as a reference for the general case:
it may guide users to sacrifice convenience and features over
unnoticeable performance gains.

Cheers!
