Which CPU for heavy traffic with much filtering/shaping?
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
HiI have a router with a large number of iptables rules and some extensive traffic shaping (HTB + RED + ... ) + conntrack.
The router is running Centos5 on a P4 Celeron 2.4 with 512Mb ram 30% soft interrupt cpu utilisation 7000 packets/second on each of eth1 and eth0 (forwarded packets) 20Mbit/second on both eth1 and eth0 e1000 ethernet on both eth0 and eth1 (eth1 running at 100Mbit)I am trying to optimise the firewall rules and have already managed to reduce cpu si by about 40% however I need to get this router to handle a throughput rate of 100Mbit or more.
I have seen hints that using SMP (or multicore) processors will not help for soft interrupt. My question is this:
1. What processors should I be looking for in order to achieve the best routing throughput on a linux router?
2. Is it true that multicore processors will not help much in this situation?
