[OpenSIPS-Users] OpenSIPS performance tests

[Chris Martineau]

Hi Vlad,

Noticed the auto_aliases is default on so I will try switching this off,
however as you have not set it otherwise in your scripts this must also
be on in the test scripts?

Many thanks


Chris

Hello Chris,

In the tests we performed we used SIPp as the UACs and the UAS was an 
OpenSIPS. In spite of this, I doubt that the UAS SiPp in your scenario 
would be the limiting factor.

You could try the load debugging patches available in trunk ( more info 
on this can be found at [1] )
to see what exactly is the limiting factor. I do not think the problem 
is the hardware you are testing on, as an dual core Intel with 4Gb of 
RAM should support plenty of traffic.

As Adrian pointed out, it is much more likely that external queries, 
like DNS, SQL or Radius are the bottleneck on your system. Make sure to 
have OpenSIPS run in fork mode with enough children, and try the load 
debugging features to pinpoint your problem.
