Just few days back MMS CR6 was released with much improvements on performance. I did a quick performance test of CR6 using SipP tool for load generation, a wonderful tool called sysstat for CPU recording http://pagesperso-orange.fr/sebastien.godard/tutorial.html#section1 and our own tool for RTP Jitter recording.
The test was run for approximately 10 min with intention to measure the jitter at load of 100 ~ 110 concurrent announcements and at same time measure the CPU usage on MMS Server.
While the Jitter was under control the CPU never crossed more than 25%. The attached graph shows the idle% CPU recorded after every 5 secs.
Here are the jitter graphs taken randomly while running the test tool.
