I'm faced with some poor ZFS RAIDZ performance on my FreeNAS 8.2 (Release) server.
My hardware:
Asus P8B-E/4L
Intel Xeon E3-1270 @ 3.40GHz
16GB (4x 4GB) 1333MHz, EEC DDR3
Asus GeForce GT 520
IBM M1015 RAID Controller flashed with LSI 9240-8i IT-firmware
7x Western Digital RE4 2TB in ZFS RAIDZ (not RAIDZ2)
1x Intel 520 SSD 60GB for FreeNAS
2x Intel 520 SSD 60GB for ZFS Log
When utilizing Samba (CIFS) to my Windows 7 desktop system I'm faced with anything from a few hundred KB/s to perhaps a maximum of 40MB/s when transferring mostly large files (like 8GB+ M4V etc..) which I find to be quite low considering the hardware and the disks.
When I played around with NAS4Free (which ended up bugging out, which is why I'm back on FreeNAS) on the same hardware running ZFS RAIDZ I was only bottlenecked by the network interface and was seeing about 95-110MB/s writes and for some strange reason 50-80MB/s read. Now with FreeNAS I'm seeing a maximum of 40MB/s writes, and about the same in reads.
Is there some hidden tricks and secrets that might improve my performance?
