Hi Valentin,

   Okay, I don't know if I can send this info on the newsgroup...  I'll 
do it anyway as it is small.  Sorry for the HTML formatting, I wanted 
the output to be as clean as possible...

   The tests were done with my 3 usual rules:

       - 00050 allow ip from any to any
       - 00090 divert 8668 ip from any to any via rl0
       - 00100 allow ip from any to any
       - 65535 deny ip from any to any    (default ... of course)

   We see clearly that my system isn't stressed at all.  We can even see 
that with rule 50, my system gets more interrupts.
