I built a Nexentastor server (free edition) and I am having serious disk performance issues.
This same box had FreeNAS on it before and it was much much faster.
Here are the specs: Dual core E6600 cpu 4GB of good memory 6x 1.5TB Seagate drives plugged into the ICH10 controller (no raid) ZFS (version 24 I believe)
I installed pure-sfv and unrar.
a pure-sfv check on a ~1GB folder takes a few seconds, this is nice and fast, no problems.
But the unrar on the same files takes forever (~7-8 minutes)
I took the same folder and moved it to a linux laptop (dual core, 4GB of ram cheap 160GB disk) and the unrar only takes 30 seconds.
Any ideas what can be causing this?
When I view the load while extracting the disks are going 200-6000KB/s read and about 2000KB/s write, the cpu is at about 10% (8-10%)
This just does not seem right to me.
Could it be unrar being silly? compile issue perhaps?
