Hi Everybody,
I did a lot of searching on Google and reading the posts in the Freenas forum, but i couldn't find the answer to my problem.
I have a wired gigabit network with a linksys WRT320N router and cat6 cables connecting the different computers. The freenas server runs on the 8.3.1 64 bit release (latest version) and has the following hardware:
- CPU: Intel Pentium G2020 Boxed
- Mobo: ASRock B75 Pro3-M
- Memory: 16 GB Corsair CMV16GX3M2A1333C9
- NIC: intel Pro/1000GT Gigabit Network Card
- hdd: 3 1.5TB Seagate Barracuda 7200.14 ST1500DM003 hard disks
For the test I have setup a ufs volume with 1 disk, so that i could see the maximum transfer performance of my system. For file transfer i have created a CIFS share.
The max transfer speed i got when testing with jperf was 40.5 MBytes and that is a lot lesss than i expected to achieve.
I ran the following test to identify the problems:
ifconfig shows the following output:
Ethernet autoselect (1000baseT <full-duplex>)
iperf -sD (with jperf TCP cllient)
Client connecting to 192.168.1.119, TCP port 5001
TCP window size: 0.01 MByte (default)
------------------------------------------------------------
[216] local 192.168.1.112 port 58042 connected with 192.168.1.119 port 5001
[ ID] Interval Transfer Bandwidth
[216] 0.0- 1.0 sec 40.2 MBytes 337 Mbits/sec
I ran the jperf test from several computers (not at the same time) and this was the best result.
dd if=/dev/zero of=/mnt/nieuw/temp bs=2048k count=1000
1000+0 records in
1000+0 records out
2097152000 bytes transferred in 16.248405 secs (129068176 bytes/sec)
I hope someone can point me in the right direction of finding a solution.
Thanks for your help!
Regards,
Martijn
