Looking through the patches it doesn't look like the SIMD re-enablement made it into this release. It is merged into master, so it may to just have to wait until 0.9.

Is there a way for a regular user to check this? Like on a running machine. I looked around in dmesg, /proc/spl and /sys/module/zfs but there's no hint.

for raidz, yes

cat /sys/module/zfs/parameters/zfs_vdev_raidz_impl
[fastest] original scalar sse2 ssse3 avx2

edit: a non-simd system wouldn't show sse or avx.

there are other facets of zfs that use simd like fletcher4 which is used for checksums, but there doesn't seem to be a way to figure out what implementation that uses.

With this being the first release since ZoL 0.8.1 back in June, ...

Lol, of course this is the first release since the last release. But that is always true. Normally you would say
"With this being the third release in the ZoL 0.8 series", you get the idea.

In the meantime, still no zfs for CentOS 8

Really cool . I can finally update to Linux 5.3 . Many thanks to everyone involved with ZoL .

I'm hoping that ZSTD support makes it for the 0.8.3 release. It actually implements zstd fast and zstd fast is just as fast and compresses better than LZ4 according to my tests.

On a side-note, when the kernel's ZSTD implementation gets fast support, that's going to be a real game changer for zram & zswap.

I really like that with zstd, a single compressor can handle the entire range from low-CPU fast compression (with decent compression ratio) all the way to extreme CPU load slow compression and very good compression ratio.
