Hi,
I have played around with freenas for a wile now, and used it in a vm on my htpc for backups.
After i did some research i decided to get a dedicated freenas box with these specs:
freenas 8.3
asrock b75 pro3 (cheap and has 8 compatible sata ports)
intel i3-3220 (dualcore with HT@3.3GHz)
16Gb ram
6x WD 2TB EARX that i already had
I did set up the disks in a raidz2 and dd (with bs=2048k cont=50k) gives me writes at 284 MB/s and reads at 295MB/s
BUT
I cant get CIFS run as fast as i hoped. I tried all kinds of settings in the gui after reading on the forum and the top result is
65MB/s reads
95MB/s writes
What i have played around with are the settings in the cifs service settings. RW support AIO sizes and so on
The highest cpu load on freenas i have seen in the reporting tab is about 43% so i guess that shouldn't be the problem.
I tried turning of hyper threading with a little bit lower results.
I tried a intel desktop 1000 pci nic without any difference.
The desktop has a sdd raid0 and can read files at about 110-120MB/s from my AMD E35 htpc so the bottleneck shouldn't be there.
I put an older ssd in the freenas box and the speeds are the same to the ssd too.
Somehow it feels that the problem is network related, when i copy the same file multiple times (i guess freenas cashes the files in ram) the transfer speed is rock steady at 67% when checking the task manager on my desktop.
Does anyone have an idea what i can try to get my speed up. Ore maybe a link to a thread i can read to get some ideas?
Sorry for my bad english and thanks in advance // Erik
