We like to run Freeswitch as a non privileged user, due to
security concerns. So there are drawbacks here compared to running
FS as root? Can we somehow quantify the differences?<br>
<br>
Best regards<br>

forks his processes?<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hey guys,<br>
<br>
I have a question about freeswitch process/threading
usage.<br>
So far that I haven't noticed freeswitch to fork himself,
I have only 1 freeswitch instance.<br>
<a moz-do-not-send="true"
href="http://i.imgur.com/bdbYOwp.png">http://i.imgur.com/bdbYOwp.png</a><br>
<br>
But then I found screenshot of htop with freeswitch and
noticed that there is multiple freeswitch processes being
run:<br>
<a moz-do-not-send="true"
href="http://i.imgur.com/VNpl55z.jpg">http://i.imgur.com/VNpl55z.jpg</a><br>
<br>
I'm having issues with "loading" the freeswitch after 50
cps in any cpu/ram configuration.<br>
Be it physical or virtual environment I cant pass the 50
cps mark.<br>
I have strange issue with CPU usage on same CPS:<br>
<br>

<a moz-do-not-send="true"
href="http://i.imgur.com/mWRnoGr.png">http://i.imgur.com/mWRnoGr.png</a><br>
<br>
I timeload test freeswitch with 50cps for 5+ hours, and
seems like there is some kind of leak somewhere.<br>
I have tested configuration on:<br>
Debian 8<br>
2 core/8 gb ram<br>
4 core/8 gb ram (graphs are from here)<br>
8 core/32 gb ram<br>
<br>
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.<br>
<br>
Test is:<br>
sipp -> freeswitch -> sipp<br>
<br>
Just 1 dialpeer with bridge action. No gateways. Just
simple dialplan and 1 profile...<br>
Any advice?<br>
<br>
Thank you all<br>
<br>
<br>
