Hi, Agalya!
A successful stress test should highlight a bottleneck that we are no
longer able to easily fix. Common bottlenecks with any network server
application will always include:
- CPU
- I/O (disk / network)
Most often, disk writes are to blame, either through stderr or syslog.
You will definitely want a very low logging level (log_level = 1) when
doing thousands of CPS, as even a single log line per request can lower
the overall throughput.
Choosing the right compile flags can also help. You should print the
output of "opensips -V", maybe improvements can be made.
To conclude, please try to understand the bottleneck first (by using
"top", "netstat", "vmstat", etc.), then we can start working on it!

Hi Bogdan,
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 with
pause of (24 to 45 sec), I could reach only 150cps.
When I tried to increase *S_MEMORY and P_MEMORY to 1024 and
64*respectively, and having opensips *children =12*, I could achieve
800 cps.
I have also re-tuned OpenSIPS log file, by adding
“-/var/log/opensips.log”.
When I see opensips performance with default script I see you are
achieving 9000cps.
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.
Am running on VM, with 8 core CPU, 16GB RAM and processor is Intel
Xeon E312xx(Sandy Bridge).

Agalya
