Hey guys,

I have a question about freeswitch process/threading usage.
So far that I haven't noticed freeswitch to fork himself, I have only 1 freeswitch instance.

But then I found screenshot of htop with freeswitch and noticed that there is multiple freeswitch processes being run:

I'm having issues with "loading" the freeswitch after 50 cps in any cpu/ram configuration.
Be it physical or virtual environment I cant pass the 50 cps mark.
I have strange issue with CPU usage on same CPS:

I timeload test freeswitch with 50cps for 5+ hours, and seems like there is some kind of leak somewhere.
I have tested configuration on:
Debian 8
2 core/8 gb ram
4 core/8 gb ram (graphs are from here)
8 core/32 gb ram

and in all the tests I were not able to send more than 50 cps without CPU dropping to 0 with all system starting to respond really laggy.

Test is:
sipp -> freeswitch -> sipp

Just 1 dialpeer with bridge action. No gateways. Just simple dialplan and 1 profile...
Any advice?

Thank you all
