Hi David, Sorry for sooo long delay. Still, it may worth answering this for the other community members.
To date we have no standard test for testing performance of the whole sipXtapi stack. But practice shows that most of the CPU consumption comes from the media processing inside sipXmediaLib. And here we do have some ways of performance measuring. First one is MpCodecsPerformanceTest in sipXmediaLib's unittests. It will give you some insights on how much encoding/decoding costs on your system. Enable it in the build and tweak its settings to get real values. E.g. set NUM_PACKETS_TO_TEST to some high value, adjust FRAME_MS to the frame size you use in mediaLib (it's 10ms by default, while FRAME_MS suggests 20ms). Second one is mstream example application in sipXmediaAdapterLib. It can be used to create many RTP streams and flowgraphs and then you can use any CPU load monitoring utility to measure performance. We have an advanced version of mstream on hands not checked in to svn and a python script to measure CPU load under Windows and Linux. If there will be an interest coming from community, we'll work on checking this into svn (probably with your help ;) ).
