There recently was an issue where the deprecation of a kernel header (with version 5) lead to ZFS losing access to hardware accelerated (vectorized) checksums [1].
As far as I know, the issue is now resolved, but I haven't followed this closely.

- vladvasiliu 4y agoYes it's been resolved. It was around the time kernel 5.16 came out, but it took a while for the fix to land in stable. I actually followed this closely, since that's when I had got a new Laptop with a new SSD and when I tried to benchmark it, I was going crazy trying to find the culprit. Because an older PC with a slower ssd (and older kernel at the time of benchmarking) was something like 25 times faster.
