Hi Vincent I agree with Peter that the best way to get maximum performance is Bare Metal. Have a look at this link when it comes to virtualization if you have no other options. http://dtrace.org/blogs/brendan/2013/01/11/virtualization-performance-zones-... I prefer OpenVZ, but haven't done any stress testing yet. My bet would be that the performance will be better in Containers/Jails then any other form of virtualization. -- Rgds
Vincent Xia <mailto:gmangudai@gmail.com> June 20, 2013 7:47 AM my network card: Intel(R) PRO/1000 MT Network Connection, and all calls have the media going through FS(everything is in the same LAN), cuz sometimes i need to do recording, but no with stress testing, as it will make significant burden to the system.

What network card hardware are you using? UDP packets on cheap networking cards are very sensitive to a lack of idle cpu time. I've seen many models of RealTek cards that will start dropping over 10% of all UDP packets if your CPU idle drops below ~50%. In my experience server grade Intel network cards are much better, but even these will start dropping ~5-10% of UDP packets if your CPU idle gets below 15%.
Also do these calls have the media going through this box? or through an external media gateway?

Can you try it on a more powerful machine?

<param name="max-sessions" value="2000"/> <param name="sessions-per-second" value="100"/>
but things didn't get any better, the host CPU usage rate is around 80-90%, memory usage: 10%, network load 10%, so i think there should be someway we can make FS handle more concurrent calls, any ideas? _________________________________________________________________________ Professional FreeSWITCH Consulting Services: consulting@freeswitch.org http://www.freeswitchsolutions.com
