Stress testing Network Card

[Voy]

Hey all,

 

Is there a way to stress test network card?

I need to stress test Mellanox ConnectX 6 card.

I think theyre are a few internet stress tests online.

are you running Linux? and do you have another server nearby with the same NIC and can you just run an interconnect between them?

otherwise if you must stress it over the network you are limited by the speeds of that network and the devices in between.

Hmm okay.

I am running windows.

Is there a software I could use?

I can connect it to it self just to have traffic going.

iperf3 should do.

That's probably not going to work as the network stack will know its the same device and bypass the physical network entirely.  Even if that could work, I'd argue you want something closer to a real-world scenario if you're looking to see if its going to work in the real-world.

 

You're only going to stress test between two different machines, so you'd have to look at details stats if you then have a problem to figure out which side was causing the problem.
