So I've dug up an old computer with a Athlon 64 3000+ processor, with some DD2 which freenas is showing 5103MB, using onboard NIC and everything connected to an unmanaged gigabit switch. The NAS works okay so far, but I kind of expecting a little bit more, for example when doing a large batch of files copying, should not cause lag streaming video on another computer - both using SMB.
What I've noticed or tested so far is...
I am open to hardware upgrades. Because this is an old machine - a lot of components that are upgradable like RAM and CPU - is definitely cheaper to get the newer gens - AMD FM2 with DDR3. So I need to weight in whether it will give me a substantial increase in performance (20%-40%) increase. I wish there's some kind of comparison chart for me to see what is acceptable speeds.
Any thoughts anyone?
What I've noticed or tested so far is...
- from freenas reporting charts, cpu usage always hits over 100% when I copy files into the server (not sure how it can go over 100% especially its a single core)
- I am not saturating the gigabit network yet. I did an iperf but its fluctuates greatly. So I did 100 counts and took the average which is 482 megabit (max 663, min 114) when no one is accessing the NAS
- There are two pools one 3x640mb and another one 3x3tb
- file compression = lzjb
