If you are meaning in term of Packet per second, you are right. These are t= he packet per second measured during tests: 64 byte: 610119 Pps 512 byte: 516917 Pps 1492 byte: 464962 Pps > Am I correct that the maximum you can reach is around 639,000 packets > per second? Yes, as you can see the maximum is 610119 Pps. Where does this limit come from? > Also you are not routing the traffic, but instead the server handles > the requests itself and eat CPU to reply? Correct. In these first tests I want to "tune" the system, so I am using th= e (let me say) worst scenario. > > _______________________________________________ > > freebsd-performance@freebsd.org mailing list > > http://lists.freebsd.org/mailman/listinfo/freebsd-performance > > To unsubscribe, send any mail to "freebsd-performance- > unsubscribe@freebsd.org > > " > > -- > Best Wishes, > Stefan Lambrev > ICQ# 24134177 > > > > Questo messaggio e i suoi allegati sono indirizzati esclusivamente alle per= sone indicate.
