Hi,
I am running a VOIP application on Centos 5.3. It is a 16 core box
with 12 G of mem and all what it does is passing packets.
What happens is that at around 2K channels running g711 ( 64k) codec,
all eth0 is used up and no more traffic can go through.
So that's about 128Mbits per second not counting UDP packet overheads
I guesstimate that you cannot get much more than that through a 1G
ethernet NIC - it is not CP bound, rather you are nearing the capacity
of a single NIC.

I have checked google and it talked about interrupt scheduler.
does anyone know how to configure the kernel to allow it to use all
CPSs for socket transmission of UDP packets?
Any pointer will be greatly appreciated.
