Anyway from the coding point of view I'm almost ready, the testing will be more difficult.

Hello Andrei,
I might help with testing and providing some performance numbers. Unfortunately I only have access to some quad core Xeon servers, not 8 cores. If the weird UDP behavior appears also on 4 cores(less lock contention), I can run a test plan.
My idea is to have several UDP workers (I plan to use 8- this will allow the kernel to distribute them evenly on all 4 CPUs - as the machine is idle). I plan to test using other 2-3 machines for sending SIP messages (using sipp or sipsak). Ser will just send some replies with some error code. I will measure the throughput over a 1 minute interval on the ser machine, with both current UDP sender and the new UDP over raw sock sender.
If this is ok then in the afternoon I will bring some results. Any suggestion regarding the test plan is welcomed.
Cheers Marius
