| |
I have a large rule set (~53000 rules) that I sometimes load using iptables-restore. (It takes almost an hour.
Googling around tells me that the loop detection code in the kernel is slow with large rule sets. The only thing that seems odd to me is that throughout the entire loading process, iptables-restore is consistently at about 67% user and33% system processor time according to vmstat. If the slowness is in the kernel, shouldn't I be seeing a high and ever increasing amount of "system" time?
Kernel is 2.6.9-1.681_FC3. Iptables is iptables-1.2.11-3.1.FC3.
