Ok, I dug myself out. :)
I have oprofile working, and I wrote a simple application to measure
received pps on the receiving box with gettimeofday() accuracy. To
reduce noise I am profiling for one minute periods. The sender is
capable of sending about 315,000 pps via an e1000.
So, which kernels shall I try? When I set the thing up I was using
2.5.70-bk14, but I am compiling 2.4.71, and I will try with your patch
above and with Alexey's.
