Hi,

This paper is a nice read:
http://www.google.com/url?sa=t&source=web&cd=6&ved=0CE0QFjAF&url=http%3A%2F%2Fcourseware.ee.calpoly.edu%2F3comproject%2FPublished%2520Papers%2Fsecurity.pdf&rct=j&q=iptables%20netfilter%20latency%20paper%20pdf&ei=2pI_Tu-VKITJswbov5Qg&usg=AFQjCNFjUZwGHDhdBhtxwQgqlQbYCMjBFw&cad=rja
It's very detailed on the issue of rule overhead (Conclusion 5.1 b).
Unfortunately paper is from 2002. Since then most of the code was
rewritten. Maybe we, as netfilter community, should lobby some
university professor to let his students do a *remake* of this
work ;-). Anyone here with ties to education sector?
Best regards,
Marek Kierdelewicz
