I have just built my first FreeNAS. Here are my Hardware specs
1. Processor: AMD Athlonx2 7750 BE @ @.7 Ghz
2. Motherboard: gigabyte GA-MA78GM-S2H
3. 8 GB RAM
4. On board NIC: Realtek 8111C
5. switch: TP-Link TL-SG1005D 5-Port Gigabit Switch. Switch supports Jumbo Frames
6. 4 Western Digital Green WD20EARX 2TB 64MB
7. Freenas is connected to switch via cat5e Cable, 2 M length
8. Client is connected to switch via Cat5e cable, 1 M length
Software specs:
1. Freenas 8.0.4 AMD64 (10351)
2. No tweaks on freenas
3. Client: Windows 7 ultimate, core2duo e8200 @ 3 GHz, 2 GB memory, Atheros 8151 integrated NIC
4. Testing methodology, Intel NAS performance toolkit V 1.7
I have tested various scenarios with different hard drive configuration. I am uploading the spread sheet as an attachment. Kindly refer for viewing performance and giving suggestions.
General copy from windows client to freenas for a 5.8 GB file varies from 45-51 MB/s with 4 disk RAIDZ. Haven't checked the read speeds yet. But i think write speeds can improve.
List of things i have checked:
1. Both the client and freenas are running at gigabit speeds. I know it because the switch indicates it (Green for gigabit and orange for Megabit connection)
2. vfs.zfs.prefetch_disable is set to 0 (checked via ssh command shell)
3. Client is not running with jumbo frames. (checked by going to Manage network adapter>atheros 8151>configure>jumbo frames = disabled) I could have enabled it but wasn't sure what should jumbo rates be. Moreover i am not sure about configuration of NAS NIC. As far as i know, jumbo rates should both be matching on client and host.
4. Ifconfig -a output for NAS box is
My questions are:
1. Is my NAS performance optimum or i require tunning?
2. If tunning is required, what needs to be tuned?
3. for enabling jumbo frames on Freenas what needs to be done?
