Hi guys,
so I think my read performance off my NFS shares is pretty bad. I'll start this with
First off my system, so that you guys know what you are dealing with:
CPU: Intel Core i3-4160, 2x 3.60GHz, boxed (BX80646I34160)
RAM: 2x Samsung DIMM 8GB, DDR3L-1600, CL11, ECC (M391B1G73QH0-YK0)
Mainboard: Supermicro X10SLL-F retail (MBD-X10SLL-F-O)
Storage: 5x Western Digital WD Red 4TB, 3.5", SATA 6Gb/s (WD40EFRX) as RaidZ2
OS: FreeNAS 9.3 on a Verbatim Store 'n' Go V3 Max 16GB, USB 3.0 (49805) (plugged into USB2)
(if you need the rest like case, fans, psu and so on, just ask!)
I headed to the storage subforums in here and read about the dd tests, following result:
[root@freenas] /mnt/mydata/Inbox# dd if=/dev/zero of=tmp.dat bs=2048k count=50k
51200+0 records in
51200+0 records out
107374182400 bytes transferred in 21.299636 secs (5041127546 bytes/sec)
[root@freenas] /mnt/mydata/Inbox# dd if=tmp.dat of=/dev/null bs=2048k count=50k
51200+0 records in
51200+0 records out
107374182400 bytes transferred in 11.048935 secs (9718057262 bytes/sec)
Also a move "on" the system looked very good to me:
Also, when I copy files onto the freenas system, I'm getting somewhere around 100 MiB/s most of the time (though the speed goes up and down between 40 MiB/s and 100 MiB/s sometimes). Besides the drops still good.
But now the "fun" part:
I don't use windows and have mounted the shares as followed: (snipped from my linux system, fedora 20)
Do you guys have any Ideas what could be a problem? I actually suspect the NFS parameters, but I'm not that experienced in finetuning them. I'm happy to provide logs if you tell me which ones you want!

This is all looking pretty good from my point of view (please correct me if I am wrong here!)107,374,182,400 100% 500.30MB/s 0:03:24 (xfr#1, to-chk=0/1)

When I try to copy files onto my linux desktop or on the freenas box itself (from one share into another, analog to the rsync test) via NFS (and also ftp and sftp) I get a maximum transfer rate of about 1,1 MiB/s. Even if the files basically do not leave the freenas box. I tried a reboot of both desktop and freenas, but that did not solve the case....
