This was nice (support has ended, but still runs):

Comparisons with other things would be interesting.

This is a bit of a blast from the past question.. Back when Beowulfs
were the “new hot thing”, we all used Ethernet as the interconnect
There was a bunch of traffic on the list about measuring Ethernet
performance using various utilities, and all the ways to optimize the
performance (zero copy Ethernet drivers and the like, some interfaces
just being slow, etc.).
What’s the current strategy and tools for looking at the Ethernet
stack and identify? I have a colleague who is working with a software
radio peripheral (USRP) that streams samples out, and he’s getting
better performance with USB3 than with GigE - it may be that this is
just the way it works USB is dedicated master/client, while GigE is
peer to peer. So I suggested he do some back to back testing using a
pair of PCs to know what the limit is.
And he turned it around and asked “so what tools can I use?”
iperf?
netcat?
I’ll dig through the archives too..
