Can you expand a bit? Do you mean no iptables to running some rules, or |
| 2 |
a few rules to a lot of rules, or general wildcards (e.g. CC) compared |
| 3 |
to individual targets? |

I have noticed a slight increase with > 2000 rules, but its quite |
| 6 |
noticeable >6000 rules (adds a ~200ms or so to latency) |

* why so many rules: one of the kids ran a downloader program that |
| 9 |
included bittorrent and the drop script happily blackholed each connect |
| 10 |
with an individual rule. I only discovered it by accident (checking the |
| 11 |
logs) - everything was ticking over quite nicely! |
