SubjectRe: kernel 2.4.2 network performances
Hi Jerome.

As Mr. Hafting says, is seems that there is a softirq missing somewhere.
If this is the case, it should help to make some add some systemcalls in
your program, since a softirq should happen at every system-call exit.

Try adding:

getpid();

in the innermost loop, and see if it helps.

I would be happy to look deeper into it, so if you could send me your
test program and I'll see if I can find anything. Please append the
result from the code with and without the getpid call.


Regards
Anders Fugmann
