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
