| In lay terms, these reports confirm that read speed is 5,520 MB/s, or 5.5 GB/s, and write speed is 1,603 MB/s, or 1.6 GB/s. This is a 4x improvement for reads and 2x improvement for writes compared to zfs. For whatever reason, zfs was not benefitting from the parallelization. It's possible that I could get zfs to perform better with tinkering, but why? Every major upgrade I have to re-compile it with dkms against the new kernel headers, which takes forever.
