Paul, We are running a number of C2D boxes at 2.4Ghz and can hot about 180KPPS with only 1 state. But when you hit roughly 10K states we are pulled back down to 160K. This is at 100% utilization. The web interface and SSH are not available at this rate and, while there is no packet loss, or serious increase in latency, the system is otherwise useless.

Would we be able to manage 160,000 pps? thanks, Paul -- Newsflash: following a catastrophic devaluation, 101 in binary is now worth just 5 in decimal - Stob. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
