Hi, Agalya!
I've just written an article about dimensioning OpenSIPS memory on the
OpenSIPS blog[1]. Perhaps that can help you.
To do further debugging, you should add some thresholds warnings to
determine what function spends most of the time processing. You can do
this by using msg thresholds[2].
Its also a good idea to check how DNS behaves on your system, using the
dns threshold[3].
Also, monitoring statistics, like memory and load might be useful for
your debug. Also, make sure bandwidth is not a problem either!
PS: for the test in the article I used my personal laptop (2 cores, 8GB
RAM) and reached 500CPS with 20 children.

Hi Bogdan/team,
Am using opensips 2.2.2 version and using opensips as only proxy.
In the default script, in route[relay], I have called setdsturi(); No
other changes with the default script.
Earlier, I have used only the default value of S_MEMORY and P_MEMORY in
the /etc/default/opensips.
With this default values, for the end to end established call , I could
reach only 150cps.
· When I tried to increase *S_MEMORY and P_MEMORY to 1024 and
64*respectively, and having opensips *children =24*, I could achieve
1000 cps.
· I have also re-tuned OpenSIPS log file, by adding
“-/var/log/opensips.log”.
· I have set the log_level =1
When I see opensips performance with default script I see you are
achieving 9000cps.
Am running on VM, with 8 core CPU, 16GB RAM and processor is Intel Xeon
E312xx(Sandy Bridge).
*What are the places I need to take a look to tune up still, to get more
performance. Your expertise would help me a lot. *

In this particular test, I am not performing any DB operations /REST
operations.
This is pure proxy, using default script.
Regards,
Agalya
