Mobicents JAIN SLEE at 900 CPS!

With respect to SLEE 2.2.1.FINAL testing, I ran the usual single node SIP UAS load test, but this time it was pushed till 900cps. First time ever, there was 2.5M calls at that load without a single call failure, just a few retransmissions, memory was rock solid at 83%, and CPU at 270% (4 Cores), during that time. The test was done in the usual old QA Labs machine, compare it with the load we handled in last 1.2 release, a bit more than 200cps!

The question now is... Will Mobicents SLEE 3.x reach the special 1K? :)


  1. A bit more concrete on config, the only changes in default config is
    turning off event router stats collection and activity idleness
    management, and of course, log4j root category is set to WARN level.

    The $JAVA_OPTS were

    -Xms8900m -Xmx8900m -XX:+UseConcMarkSweepGC
    -XX:CMSInitiatingOccupancyFraction=80 -Xmn256m -XX:MaxPermSize=256M
