[OpenSIPS-Devel] OpenSIPS performance tests

[Vlad Paiu]

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
