CPS stands for Calls Per Second.  Which basically means, the number of "new call attempts" that are hitting "every second".

Suppose you have 1 call attempt coming in every second.  After 30 seconds, out of the 30 attempts in total, only 10 were successfully connected.  That would still make your CPS = 1.  So, having 10 "active sessions" is not important.

The CPU has the most work to do during call setup, as it has to process the logic of establishing the call.  However, once the call is connected, there is very little "logical processing" for the CPU.

I am sorry but I dont understand the difference between cps and number of active session.

If fs has 10 active sessions (with media), then the call per second should be 10 too??

That would seem like a reasonable thing to do.....

In my (limited) experience there are two important things to control:

1) call per second
2) Total number of active sessions

Calls per seconds appears (to me) to have a greater effect on the CPU. So at 1 call per second I would be looking at your CPU utilization and if it is maxing out then reducing that rate.

My point being here that your box *may* be capable of handling 100 or 1000 sessions, if the cps is lowered.
