Re: Could zfs use a gpu or x86 mmx instructions for speedup?

It does use SSE/AVX for various things, which are MMX's bigger, badder
siblings.

Conceivably you could try using a GPU but you'd be a little hard-pressed to
make it a win in some scenarios since you have a nontrivial overhead from
round trips to the GPU and back, which you usually try to hide by doing
lots of operations in one copy at once, but then latency might be exciting.

You could also look at the discussion on OpenZFS around ZIA or the Intel
QAT integration for gzip.
