TrueNAS 3xSSD drives pool configured as RAIDZ no compression DEDUP=YES I'm getting above performance. It is constantly dropping with the speed after running about 10s with full speed.
When the same 3xSSD disk are configured as stripe (aka one disk), exactly the same disks the performance is as expected 1Gib (my network).
So, obviously, something is not right with the RAIDZ pool setup.
What am I doing wrong?
CPU is ok. I have 32GB of memory. The only difference on same hardware is stripe/raidz both dedup.
performance drop is >15s and full-throttle lasts about 10s
Version:
TrueNAS-12.0-U7
Latency and disks busy for same RAIDZ Pool with 3xSSD disks.
