I've searched the forums on this, but all I seem to find is posts on ZFS, ESXi and iSCSI, so I'm a bit confused as to if I should be following the same tips?
My Config is
FreeNAS 9.2.1.6
To this drive I'm getting what I think to be OK'ish performance on Crystal Benchmark (1 gb file)
SEQ
Read 323.4
Write 451.5
512K
Read 320.2
Write 260.8
4K
Read 9.948
Write 19.77
4K QD32
Read 230.9
Write 209.5
Then on the Windows PC I am running Hyper-V with the VM's disks on the iSCSI drive.
The problem is I'm getting terrible disk I/O on the VM's? I'm seeing this in the Task Manager on the VM, sort of 2MB/s with the odd burst. Copying big files is better, 50MB/s odd, but still not great.
I'm assuming this is because its lots of small random I/O?
Is there anything glaringly obviously bad with my setup, if not, where should I start my investigations?
Thanks in advance
