[OpenSIPS-Users] OpenSIPS performance tests

[Chris Martineau]

Hi,

Don't understand how you get such high cps. I have a scenario using SIPp
as the clients and a script similar to test_I config file. The scenario
makes a call to the far SIPp client waits 10 seconds and then sends a
bye with the far SIPp client responding appropriately. However I can
only manage a maximum of around 30cps before the 100 trying messages
from the server start to fail and the invite retransmissions start to
cascade.
I have xlog disabled and debug=0 as this grinds the system down to only
5cps when switched on.
My setup is a dual core intel with 4gb.
As you can see there is a vast difference between 30 and 6000 cps which
I can't imagine is being that drastically effected by my hardware as
processor overhead is barely touched when it fails which would indicate
opensips is introducing delay by blocking somewhere!

The system is on a basic CentoS install.

By the way I have also tried this with a stripped down config similar to
test_B with little difference in performance!

Any suggestions?

Many thanks

Chris

Hello,

We have performed some tests using OpenSIPS 1.6.4 to simulate some real 
life scenarios, to get an idea on the load that can be handled by 
OpenSIPS and to see what is the performance penalty you get when using 
some OpenSIPS features like dialog support, DB authentication, DB 
accounting, memory caching, etc.

A total of 11 tests were performed, using 11 different scenarios. The 
goal was to achieve the highest possible CPS in the given scenario, 
store load samples from the OpenSIPS proxy and then analyze the results.

The base test used was that of a simple stateful SIP proxy. Than we kept

adding features on top of this very basic configuration, features like 
loose routing, dialog support, authentication and accounting.

The detailed description of the test scenarios performed, a performance 
penalty table showing the load impact introduced by adding different 
features onto OpenSIPS as well as a graphical chart showing load samples

from all the tests can be found at
