This is an antitodum of slow write performance from 0.8.x.
Do You plan to put this to actual version of proxmox?

this has been already answered - see https://forum.proxmox.com/threads/zfs-major-performance-fix-6-days-ago.56308/

it will land in PVE once 0.8.2 is out and we have a kernel upgrade.

hope this helps!

it was not included in 0.8.2, but we have our own version with a kernel backport that is not affected by issue 9346. see PR 9406 for the current status of the upstream solution
