Thanks for this information.

Yes, I had missed this when I quickly looked at the web page using lynx.

One obvious thing that's missing in your performance and Roberto's figures
is what *exactly* are the non-matching rules. Ie. do they only match IP
address, a TCP port, or what? (TCP port matching is about a degree of
complexity more expensive with iptables, I recall.)
