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 ready0 session(s) since startup0 session(s) - peak 0, last 5min 00 session(s) per Sec out of max 400, peak 0, last 5min 010000 session(s) maxmin idle cpu 0.00/100.00Current 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.On Thu, Feb 11, 2016 at 6:16 AM, Vladislav Ivanov <deforceczt@gmail.com> wrote: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:

Anything I'm missing? Really strange that CPU drops like that...2016-02-02 17:22 GMT+02:00 Nathan Neulinger <nneul@mst.edu>:"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.
