Slow network - new motherboard?

[William Bravin]

hello all i would like to have and opinion please. I was told the the slow network throughput of my system was due to my board not being the nos recommended for freenas. therefore i am thinking of buying a supermicro x10slm+f mb with and e3 1275 v3 and 16gb ecc ram would you consider this a compatible solution that would resolve my network issue?

thank you

I would suggest you test the performance between your FreeNAS and the clients with iperf/iperf3. That will allow you to test raw network speed without bringing storage into play. If you get poor performance over your powerline units, I would try to repeat the test with something connected via regular ethernet. Powerline can be fussy when you go from circuits on one side of the breaker panel to the other. It is also possible there is something else generating some interference that is affecting the powerline networking.

Power lines make poor network infrastructure, but I think it would be required to review what you are using now and what performance level you are looking to get.
Please note that the number of drives in a system, the model of the drives, and the pool layout are more likely to impact performance in normal configuration but power lines change everything.

More than likely, you have a Realtek NIC on your Asus motherboard. An inexpensive test would be to get an Intel Pro/1000 CT (~$30 USD) and test the wired connection. As others have said the powerline network equipment is probably the biggest bottleneck.

Could you please avoid making multiple threads about the same issue:

It makes life more difficult for those of us trying to help people on the forum. The same question should not need to be answered over and over.

Hum... You should post your speeds and how you tested it. Some people think they have a slow network and it turns out they were just trying to transfer lots of small files, while other folks think they have a slow transfer rate of 88MB/s and that really isn't that slow. How you test makes a difference too. And as others have stated, a power line distribution is not very good and could be causing your problems.

thank you for your reply

I get my results from the dashboard and it gives me a down speed of 0.003MB/s sometimes 0 and up speed 0.001 at best and most of the time 0. this i was told was due to my unreliable NIC on my MB. This is why i am thinking of moving to a supermicro x10slm mb.

thank you for your reply i tried to download and run iperf3 it just opens and closes down immediately

thank you for this advice i will try it

iperf3

iperf is already in FreeNAS, no need to download it, or are you talking about running it on another computer?
