There's a paper by Ratz, referred to in the HOWTO, where he 
finds that if the packets have to pass through more than 500 
rules, then throughput suffers, but below that, there is no 
decrease. Most of the problems people have with iptables 
rules are using conntrack, which does bring the network to a 
crawl. (I can't imagine myself writing a stack of iptables 
rules 500 deep and getting it right.)
