We use a RedHat 7.3 machine as bridge on a P3 1.8 Ghz with 2 64 bits Gigabit
interfaces. On the machine we have a lot of iptables rules like :
all -- 213.134.225.0 0.0.0.0/0
all -- 0.0.0.0/0 213.134.225.0
TOS all -- 213.134.225.4 0.0.0.0/0 TOS set 0x08
all -- 0.0.0.0/0 213.134.225.4
Currently in the peak hours we have about 40 Megabit traffic. Also in this
peak hours we have a CPU load of about 70%. What is the main reason of this
CPU load, is it the high traffic or the iptables rules on the machine. And
if the iptables rules are the reaseon of the high CPU load, does TOS
mangling use much CPU?
