[Freeswitch-users] freeswitch CPU usage

[Nyamul Hassan]

One thing that you are totaly "ignoring" Vlasis, is that the performance
tests are irritating to the core-devs because FreeSwitch's CPS is already so
high, that their effort / time are better used at improving / adding other
things.  Like the new "concurrent call recovery" feature, which is just
simply crazy, if you ask me.

Just think about it, at 200 CPS, for 100% ASR (IVR) and 1 min ALOC / ACD,
you're talking about 12,000 concurrent sessions.  Or in a "real-life" call
routing scenario, at 50% ASR and 5 mins ALOC, it is equivalent to 30,000
concurrent sessions, or 1,000 E1s!

And all that, using regular, run-of-the-mill, processor, motherboard, etc.
 The server Woody mentions would probably cost around $ 6,000 - 7,000/- from
HP or IBM.  Who can beat that?  And, to top that off, Woody was comparing to
600 CPS that he got on v1.04 (36,000 or 90,000 conc. sess.)!

The core-devs are very passionate about their work.  And, they have created
a beast!  So, get the beast to work "in real life", and then complain about
problems.  I've seen them instantly jump into helping with the situation.
 Bug reports are fixed within hours.  Even the "latest GIT" is claimed to be
the most stable versions!  Not many software projects (open source or not)
can boast that, if at all.
