I would like to see what have you done yet. Here is a previous conversation about that: http://www.mail-archive.com/freebsd-performance@freebsd.org/msg02293.html Actually I am not aware of the changes in 7.2 or what could be the best value set for you, worth to try to fine tune these.

If you are meaning in term of Packet per second, you are right. These are the 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 the (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- > unsubscr...@freebsd.org > > " > > -- > Best Wishes, > Stefan Lambrev > ICQ# 24134177 > > > > Questo messaggio e i suoi allegati sono indirizzati esclusivamente alle persone indicate.
