I'm currently on 2.6.20, and have also tried 10gbe nics on 2.6.23 with
good results.  At least for my app, performance has been pretty steady
at least as far back as the .18 kernels, and probably before....

I do 64k or smaller writes & reads, and non-blocking IO (not sure if that
would matter..but I do :)

Have you tried something like ttcp, iperf, or even regular ftp?

Checked your nics to make sure they have no errors and are negotiated
to full duplex?

Thanks,
Ben
