What's the max speed on Ethernet?

I believe it has to do with the penalty going between kernel and userspace because I remember repeatedly seeing novel projects that blow past these limits suggest pushing the whole networking stack to userspace. But I could be wrong.

Interesting question, hope somebody chimes in.

Could very well be hardware- or driver-dependent, and obviously the switch or device on the other side of the cable has a say in it too. There's an awful lot of pluggable stuff in there to support everything in the market. Really this thing needs to say "I only measured 1.3Mpps between two 3.11 kernels on IVB boxes with RTL8168 devices connected via a Netlink blah blah blah switch" to have any diagnostic meaning.

He addressed the kernel / userspace limit by noting that 10GigE card performs better. At this level, I'd start checking driver settings — particularly since, as he noted, this is rather different from the traffic most things are optimized for.

Novell projects or Novel projects?
