Is
FreeSWITCH starting with root permissions? It needs this in
order to use the FIFO scheduler and access realtime threads.
If not started as root, this would explain your CPS
limitations. There are also limits that can be set in the
config files.
After
it starts it drops privileges to those specified on the
command line with –u and –g switches.
FreeSWITCH
uses multi-threading. I do not know about htop, but maybe it
is showing the multiple threads?
top
–H shows each thread.

Subject: [Freeswitch-users] Does freeswitch
forks his processes?
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
