Thanks for this information.

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