I am try use Intel 82599ES in NETMAP mode for filtering traffic.
For SYN-flood case my application can recive (by poll(2)) about
12-13Mpps by 2 thread at X5675@3.07GHz (all other traffic don't
recived by kernel).
For ACK-flood case my application can recive (by poll(2)) only about
5.8Mpss by 2 thread at same hardware. I am talk only about receive
packets, don't processing.
What is wrong?
How to packet payload influence to NETMAP performance?
