Performance optimization and stack size value
Hi List, I'm trying to make my FS server more performant and reliable, and I found the FS's wiki page telling that I can change some "ulimit" values on my system, like the Stack Size. So, I've changed in the init script the "ulimit -s" value to 8192, but now when I start freeswitch I've got the following error message :
Error: stacksize 8192 is not optimal: run ulimit -s 240 from your shell before starting the application. auto-adjusting stack size for optimal performance...
So when I check the status :
freeswitch@10.84.9.41@internal> status UP 0 years, 0 days, 0 hours, 0 minutes, 6 seconds, 661 milliseconds, 592 microseconds FreeSWITCH (Version 1.3.17 git 16289ce 2013-03-14 03:24:25Z) is ready 0 session(s) since startup 0 session(s) - 0 out of max 30 per sec 1000 session(s) max min idle cpu 0.00/100.00 Current Stack Size/Max 240K/8192K
It seems that the 8192 value isn't set and is rollbacked to 240... I've got exactly the same result when the init script is filled with "ulimit -s 240". Do you have any idea about how to have the stack size increased ? Thanks a lot, *Bien cordialement, Best Regards, **Kevin MATHY* | Ingénieur VoIP --
Why do you want to increase stack size? FS tries to keep it as low as possible. 2014-02-14 15:45 GMT+01:00 Kevin Mathy <k.mathy@hexanet.fr>:

Hi Brian et al, I just want to say that the wiki is not wrong. Although, as Anthony noted in a previous thread on this matter, FS only needs 240K to work but you still can increase the stack size to 8192K following the instructions on the wiki page without problems, as seen bellow: UP 0 years, 2 days, 20 hours, 20 minutes, 43 seconds, 191 milliseconds, 414 microseconds FreeSWITCH (Version 1.2.22 64bit) is ready 203013 session(s) since startup 89 session(s) - peak 239, last 5min 126 2 session(s) per Sec out of max 100, peak 24, last 5min 9 2000 session(s) max min idle cpu 0.00/91.00 Current Stack Size/Max *240K/8192K* Best Regards, -- *Nuno Miguel Reis* | *Unified Communication** Systems* M. +351 913907481 | nreis@wavecom.pt WAVECOM-Soluções Rádio, S.A.

Hi Peter, Anthony,
Thanks for your answers. Indeed, if I wanted to increase the stack size, it was just because of the advices written on this wiki page : http://wiki.freeswitch.org/wiki/Performance_testing_and_configurations
I'm just a bit aware of how works internally a Linux OS, and so I simply followed what was said on the wiki, thinking that it'll be OK. But in fact, it's not...
Anyway, I'll follow what you said, and let the stack size value to 240k, as FS doesn't need to use more. Thank you for this information.
Otherwise, when I make a "top" on my system, I've got the following output :

In which we can see that FS seems to use 25% of CPU ressources, but all CPUs seem to be around 7% used (all counted). So my question is : which one is the real value about CPU percentage used ?
I'm remember that FS has a function to refuse new calls if a CPU used precentage threshold is reached, and I'd like to set this value as well as possible. And for that I have to know the real usage of my CPU by FS.
Thanks a lot for your help,

Stack size is how much ram is reserved per thread open. We only need 240k and you are offering to let it use 8 megs.

Why do you want to increase stack size? FS tries to keep it as low as possible.

Hi List,
I'm trying to make my FS server more performant and reliable, and I found the FS's wiki page telling that I can change some "ulimit" values on my system, like the Stack Size.
So, I've changed in the init script the "ulimit -s" value to 8192, but now when I start freeswitch I've got the following error message :
Error: stacksize 8192 is not optimal: run ulimit -s 240 from your shell before starting the application. auto-adjusting stack size for optimal performance...
So when I check the status :
freeswitch@10.84.9.41@internal> status UP 0 years, 0 days, 0 hours, 0 minutes, 6 seconds, 661 milliseconds, 592 microseconds FreeSWITCH (Version 1.3.17 git 16289ce 2013-03-14 03:24:25Z) is ready 0 session(s) since startup 0 session(s) - 0 out of max 30 per sec 1000 session(s) max min idle cpu 0.00/100.00 Current Stack Size/Max 240K/8192K
It seems that the 8192 value isn't set and is rollbacked to 240... I've got exactly the same result when the init script is filled with "ulimit -s 240".
Do you have any idea about how to have the stack size increased ?
Thanks a lot,
