network tunning pb under kernel 2.4 ?

[Gautier Harmel <Gautier.Harmel@xxxxxxxxxx>]

Hello,

I need to flood a network with a little program which basically sends
UDP packets in an infinite loop.

Under the kernel 2.2.x there is no pb, I can flood my network by sending
my packets at 12 Mbs.

Under kernel 2.4.2 we can't flood it faster   than 4.6 Mbs !
While my CPU doesn't work too much, I guess that there is a soft limit
in the kernel, but I can't find it on the sources.

I've tried to modify  somes of the /proc/sys/net/ without success.

thank you very much for your help,

Gautier
