I have changed it: <param name="sessions-per-second" value="400"/> If there was limit - there would be no CPU hogging. Here is status command: FreeSWITCH (Version 1.6.6 git d2d0b32 2016-01-11 20:16:12Z 64bit) is ready 0 session(s) since startup 0 session(s) - peak 0, last 5min 0 0 session(s) per Sec out of max 400, peak 0, last 5min 0 10000 session(s) max min idle cpu 0.00/100.00 Current Stack Size/Max 240K/8192K I can believe that i'm just DDoSing my box. I'm using simple uac/uas from sipp, and certain load is ok, but after that it goes straight down with increase of just 5 cps... I mean it is strange that with 20 cps it's 25% loaded and with 25 cps it's 100% loaded. 2016-02-11 16:38 GMT+02:00 Brian West <brian@freeswitch.org>:
I sense that your load testing method is flawed and you're just DDoSing the box.

Hey guys,
It is true, I haven't ran it as root, I fixed it. But I still have issues with passing more than 50cps, same is happening... 4 cores CPU - CPU is good, 80% idle, load average: 0.81, 0.98 This at 25 cps (I bridge the call, so cps*2) Then I add 5 cps more: load average: 1061.40, 333.52 And all OS start's lagging as hell, and i'm unable to find issue, have no idea what is happening...
My settings: http://pastebin.com/62B45z4i
Anything I'm missing? Really strange that CPU drops like that...

"Run as" != "Start as"
If you insist on not starting FS as root to let it change user, like most other daemons/services, you'll have to jump through a bunch of extra steps using file system capabilities to give it the ability to set scheduler parameters/etc that are restricted to root normally.

I've just stumpled over this:
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.
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?
Best regards Peter

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.

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. http://i.imgur.com/bdbYOwp.png
But then I found screenshot of htop with freeswitch and noticed that there is multiple freeswitch processes being run: http://i.imgur.com/VNpl55z.jpg
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:
http://i.imgur.com/8BdQWVL.png http://i.imgur.com/mWRnoGr.png
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
