Quite late reply, but here goes anyways ... You need to look at your system stats and see if the problem is CPU or I/O I just did a presentation at ClueCon about this very same thing: http://www.slideshare.net/MoisesSilva6/scaling-freeswitch-performance Using vmstats and plotting the load should be obvious where the problem is. The presentation can give you a few hints on what to change in your setup. - Moy Moises Silva Manager, Software Engineering Sangoma Technologies 100 Renfrew Drive, Suite 100, Markham, Ontario, Canada L3R 9R6 T +1 905 474 1990 x128 | toll-free in North America +1 800 388-2475 | F +1 905 474 9223 www.sangoma.com On Thu, Jun 18, 2015 at 9:40 AM, Jeevan Dhami <jonu.dhami20@gmail.com> wrote:
Hi
I am tring to benchmark freeswitch call capacity. But After 700 concurrent call load i am getting some distortion and other problems (Mentioned below). I need your help to tune my freeswitch server or freeswitch with which i can reach at higher concurrent calls.
My Setup: I have 2 servers.
*Sipp Server:* OS : Centos 6.2 64 bit. RAM . 2 GB
*FreeSwitch Server:* OS : RHEL 6.2 64 bit. RAM . 4 GB freeswitch Version 1.5.15b
*a-* when i was trying for 500 concurrent call to freeswitch using following command
./sipp -i 10.168.1.10 -sf data/uac_raj.xml 10.168.1.25:6060 -s 12345 -r 50 -l 500 -m 3000 -t u1 -inf data/number3.lst -trace_err -max_socket 503
its was working fine in following terms 1-After 500 concurrent calls load i make a call from softphone. Voice quality was good. 2- quick response from freeswitch 3-call duration was fixed for each call. (In CDR i found call duration 24 for all calls) 4-all 3000 call are successfully completed
*b-* when i was trying for 700 to 1200 concurrent call to freeswitch using following command
*For 700 calls* ./sipp -i 10.168.1.10 -sf data/uac_raj.xml 10.168.1.25:6060 -s 12345 -r 70 -l 700 -m 3000 -t u1 -inf data/number3.lst -trace_err -max_socket 703
*For 1200 calls* ./sipp -i 10.168.1.10 -sf data/uac_raj.xml 10.168.1.25:6060 -s 12345 -r 120 -l 1200 -m 3000 -t u1 -inf data/number3.lst -trace_err -max_socket 1203
*its was working fine in following terms* 1-quick response from freeswitch 2-all 3000 call are successfully completed
*its was not working fine in following terms* 1- I was getting some distortion in voice , in my test call from soft phone 2- In CDR file , call duration for all calls was varying.
*c-* when i was trying for more than 1200 concurrent call to freeswitch using following command
./sipp -i 10.168.1.10 -sf data/uac_raj.xml 10.168.1.25:6060 -s 12345 -r 130 -l 1300 -m 3000 -t u1 -inf data/number3.lst -trace_err -max_socket 1303
*its was not working fine in following terms* 1- I was getting some distortion in voice , in my test call from soft phone 2- In CDR file , call duration for all calls was varying. 3- At softphone call i was getting ANSWER response very late.
