1000baseT onboard NIC only displaying as 100M??

[Cleverking]

Hi All,

This may come across as a very noobie question however judging by the screenshot below, is my onboard NIC which is capable of 1000baseT only running at 100baseT?

The transfer speeds are usually expressed in MB/s and the speeds of the NICs are usually expressed in Mb/s. There's a ratio of 8 between them (1 MB/s = 8 Mb/s) ;)

Thanks for the explanation although forgive me for my incompetence, would that mean I would be averagely transferring at approximately 743.2Mb/s with a maximum of 1000Mb/s?

Yes. There can be a lot of factors that affect performance (your network configuration, hardware, number / size of files being transferred, etc.). The question you need to answer is "is performance good enough for my needs".

Thanks. So this is my first step of troubleshooting on why I am averaging approximately 4MB/s transfer speed over my network. I am using an onboard Intel® 82566DC Gigabit NIC (Mobo Intel DG965SSq) over Cat5e with an Apple Airport Extreme 10/100/1000. Apart from the Interface Traffic being maxed out, I can also see my memory (6GB, waiting on the other 2GB in the post) also maxed out - However somewhat pessimistic to think that the extra 2GB will make much improvements on my current transfer speed throughput.

Transfer speed may well not be limited by the NIC, but by other factors. However, the OP's graph is clearly labelled "Bits per second", so this is really only a maximum of 93Mb/s, or around 11MB/s.

You might want to start with an iperf test. On server run "iperf -s", and then run "iperf -c <ip address of server>" on a client computer.

And the million dollar question... What is your full hardware and vdev type?

Oh yeah, you're right, didn't catch that.

To the OP: what is the speed displayed by whatever window you have on the client side when you do a copy?

My guess is that you have a 100Megabit link somewhere downstream from your freenas. Maybe the client? Or a bad cable? Your FN looks ok to me.
