caveat emptor,  It's a common tactic to set up improbable situations then brag about the CPS achieved much how CPU tries to sell you on megahertz numbers.  Remember video game consoles in the 90 bragging how many "bits" ooh!!! this is 16bit blah blah.....


For instance, if i set up a dialplan on FS to instantly hangup the call and never do anything and fire sipp at it I can hit like 500+cps all day.....

Many people test their sip stack against blank call setups with no media then brag about the highest number achieved.   The bottom line is you have to consider how you are going to use the system when deciding what an impressive number is.  If every call has media for instance, if that media is being resampled or transcoded as well, how many CPU are on the host PC also.

A quad woodcrest 2.6ghz can do about 3000 simo media sessions with FS, the same box can just make it to 400 when they are all G729 transcoding calls.  If they are bridged calls, that number goes in half, if we take media out of the picture that number quadruples.  So I guess I could boast 400 CPS with 3000-6000 simo sessions, but what's the point, I'll let Ken do that...... ;)
