Hello... I have tested iptables using bridge mode. linux centos 3.x kernel 2.6.x Opteron dual CPU 2G RAM conntrack enabled When I generating lots of of packets throught iptables, one CPU upto 100% but the other CPU just idle.. and the performance degrades... As I know the performance of the iptables has relations with CPU. But, dual CPU can't help with iptables? If I set dual bridge, can use dual CPU? Anyone who can provide me with some information about how to configure SMP system, so that both processors share the traffic load?? Thanks... ____________________________________________________________________________________ Get your email and see which of your friends are online - Right on the New Yahoo.com (http://www.yahoo.com/preview)
