Poor transfer speeds < 1mb/s

[alexthefourth]

i have a freenas system with 3 2tb drives running in a zfs raid, 8gb ram, intel gigabit nic, and intel g3220 procesor. The freenas system is running off of a 2gb usb stick.

i am running freenas 9.1

i have trouble with getting good transfer speeds. i cannot get read or write to get over 1 mb/s

when running ifconfig i see that the speed is gigabit and im using cat5e and cat6 cables and a gigabit switch and router.

im using cifs shares.

how can i identify what is causing the problem?

 

[alexthefourth]

does it matter that im using a 2gb usb stick? should i use a bigger one?

It "should" be a 4GB to be safe. But normally if a 2GB won't work the system has errors and all sorts of problems besides just "slow performance".

Post the output of these commands:

zpool status
camcontrol devlist
ifconfig

The forums have code tags. You should use them

Please post a new message with the code tags - what you have isn't readable.

The output should look like a paragraph, not a one line sentence.

sorry, fixed it.

also noticed that it switches between 100basetx and 1000basetx. how can i keep it at 1000basetx?

 

[gpsguy]

What's the other end of the network cable connected to? If it's a "green" switch, perhaps that's what's causing it to fluctuate. While you're troubleshooting, try another cable.

 

[alexthefourth]

its a netgear gs605 gigabit switch. ive tried another cable with the same results, i'll try bypassing the switch and connecting directly to the router

 

[cyberjock]

If its going back and forth between 100Mb and 1000Mb then you have a problem with your hardware. Usually its a cable issue but it could be a 1/2 broken port on one end or a cable that is not being pushed in all the way. In any case, fixing that first is going to be more important than your speeds because it shows that hardware-wise something is already wrong. So we can't rule out any software issues until that's fixed.

 

[alexthefourth]

i connected it directly to the router now and its staying at 1000Mb and I tried a transfer again with improved results but still pretty bad, it went over 1Mb/s but most of the time stayed in around 700-900 kb/s

 

[Yatti420]

Something isn't right.. What motherboard?

 

[alexthefourth]

ASRock Z87E-ITX

 

[Yatti420]

I find sometimes specifying port speeds.. 1000baseTx clears things up.. Or I find these problems start by trying to specify the speeds on networks with 100basetx max devices.. I'm not sure about the intel ethernet adapter.. Have you looked for other people using this board on Freenas 8/9?

I'd probably tear the newtork down.. Check internals.. Resets etc.. Check firmwares etc.. 1 Mb/s is like 10 base speeds?

 

[gpsguy]

Also how full is the pool? Is it over 90% full?

[alexthefourth]

Theres 2tb free

what are acceptable speeds? or decent speeds? i tested on another pc and im getting around 5-8Mb/s

 

[cyberjock]

So the first thing you need to do is use iperf to figure out if this is a network problem or a server or protocol problem.

Do some iperf tests and post the results back.

 

[alexthefourth]

what is the correct way to run iperf tests? i apologize but im very new to freenas

 

[alexthefourth]

i saw this http://doc.freenas.org/index.php/Iperf

and tried iperf iperf -f MBytes but that didnt work
