I've tuned as much as I can. I still can't get this damn thing to perform. On Freenas 8.2 I was fine, no breathing. Just an upgrade to 8.3 and it foobarred so I strted to retune but cannot get it to behave without a breath time to time. I'm getting around 110-120MB read, 120MB right until it breaths then it's screwed.
I'm getting around 150MB write to the disks with testing (2 x 2TB WD drives, 2 x 1TB 7200 RPM Seagates) and 300MB read so it's not disks. iPerf is around 950mbps both ways.
This is using CIFS. I have 16GB RAM (12GB dedicated to VM and native hardware ownership in the VM) and a 4 - core 3.2 ghz intel with 3 cores assigned to the VM so I'm not hardware bound. Again, it worked on freenas 8.2, 8.3 is giving me issues.
