[Freeswitch-users] Reg. Freeswitch Performace on Freescale Board

[Varghese]

Hi Anthony,

Thanks for the information.

Kernel is Linux-2.6.32 patched by Freescale team for the hardware.

Further we tested the freeswitch-1.2.6 on Freescale and following are 
observations.

We set the ulimit options as per the wiki link and ulimit –s 240

1. With switches *-np* and *–lp* the result is same i.e. maximum of 90 
calls and top command shows 100% CPU for freeswitch process

2. With RTP Bypass mode we could make 250 calls and CPU usage is 20%

3. With Proxy media mode, and default rtp mode the CPU is very high. 
Approximately 1 to 1.5% per call and scales up to 90 calls

4. Set the option enable-timer value = false in SIP profile, 
stun-enabled=false given all IP address in ext-rtp, 
rtp-timer-name=none/soft etc., still the results are same

Q1) Can you explain “asterisk also uses blocking reads in its rtp stack 
where we have timers. You can disable the timers as documented in the 
wiki” which parameter you are referring to and where we need to disable 
timers.

Q2) Do we need to try any other options to increase the performance 
numbers?

F.Y.I, We used Empirix Hammer SIP Call Generator for testing SIP calls.

Thanks
Varghese Paul
