I was doing statefull 550k pps on Athlon64 X2 5200 cpu usage was ~50% per core. I'm doing stateless > 1m pps on Quad-core Xeon(R) CPU E5345 @ 2.33GHz, peak cpu usage is less then 25% per core both configs used e1000 nics, 1GB Ram both boxes were running BGP >I have been searching everywhere for some kind of guidelines, but I see >none.

Make your router stateless or optimeze netfilter settings related to conntrack (more memory, bigger hashtables ect) >2.0GHz Dual-Core Xeon, 4GB 667MGz RAM, 2x1Gbit Network Interfaces. Quite a lot of ram for statefull firewall + BGP (1GB would probably suffice). As for CPU diagnose your network and compare your pps with the numbers and platforms I specified. cheers, Marek Kierdelewicz KoBa ISP _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
