Softswitch performance

It is important to note that simultaneous calls depends only on hardware you are using.

2008.03.01 1575 simultaneous calls (2049 channels)

• 2 x Quad-Core Xeon 5300 "clovertown"
• 4 Gb RAM
• Debian 4.0
• 2.6.18-5-amd64 #1 SMP Tue Oct 2 20:37:02 UTC 2007 x86_64 GNU/Linux
• Asterisk 1.4.15
• canreinvite=no*
• ~15% calls with transcoding (~85% calls no transcoding)
• CPU busy 83% (17% idle)
• Comments:
  • why channels/2 != calls?
  • because not all of them was connected
  • and when the system is loaded the channels stats update slow
  • in that day we got to almost 3500 cc
  • when you have a lot of invites, the system get very slow
  • we got to 220 setup calls per second
  • and the system was very havy
  • in that load, your app was very good, however mysql become the bottlenack
  • so i had to tweak it a little bit, but we already talked about it.
  • with your app, from the time we installed, we already did more then 30M minutes.
  • this setup can handle around 4k cc easly with no high rate cs per second

• canreinvite=yes means that voice traffic goes from client to provider directly bypassing MOR system
