Can you expand a bit?  Do you mean no iptables to running some rules, or
a few rules to a lot of rules, or general wildcards (e.g. CC) compared
to individual targets?

I have noticed a slight increase with > 2000 rules, but its quite
noticeable >6000 rules (adds a ~200ms or so to latency)

* why so many rules: one of the kids ran a downloader program that
included bittorrent and the drop script happily blackholed each connect
with an individual rule.  I only discovered it by accident (checking the
logs) - everything was ticking over quite nicely!
