Question 10gbps nic only reading 1410mbps

[Lenscowboy]

Hi guys,

I have a 10gbps marvell fastlinq edge 10gbit network adapter in a ROG strix Z790A motherboard but I am only getting 1410bmps in the task manager.
I've been reading up on PCIe lanes but I am really clueless when it comes to this stuff.
Can anybody shed some light on this for me please? Is there a way to up the speed or have I been sold a lemon?
Thanks

What is this adapter connected to? Router, switch, etc.

Is your entire network comprised of 10g devices?

If this is your MB, it has 2.5GB ethernet

Some important questions:

• How are you testing?
• What is the card connected to?
• What cabling are you using?
• Are the units correct? (10 Gbit/s = 10.000 Mbit/s = 1250 MB/s)

Yes I have a 2.5gb on board adaptor.
My switch is a TP Link TL-SX30116F 10gb switch
I have 5 machines on my network. 3 of them have 10gbps cards, the one in question being one of them.

You throughput will be limited by the slowest device on your network. Like your router, cable modem, etc.

Were you measuring performance inside your network, or a site external to it?

You need to test very simply to begin with. You never really know when some disk issue or other parts of a machine might be the problem.

I would use a very simple line mode tool called IPERF and see what rates you get between machines in your house.

I know it works fine on slower ports like 2.5 or 5g but 10g is a lot and you start to worry about stuff like shared PCIE lanes etc.

IPERF though should test much higher than 1.4gbit.
