[OpenSIPS-Users] opensips performance

[Răzvan Crainea]

Hi, Agalya!

I've just written an article about dimensioning OpenSIPS memory on the 
OpenSIPS blog[1]. Perhaps that can help you.

To do further debugging, you should add some thresholds warnings to 
determine what function spends most of the time processing. You can do 
this by using msg thresholds[2].

Its also a good idea to check how DNS behaves on your system, using the 
dns threshold[3].

Also, monitoring statistics, like memory and load might be useful for 
your debug. Also, make sure bandwidth is not a problem either!

PS: for the test in the article I used my personal laptop (2 cores, 8GB 
RAM) and reached 500CPS with 20 children.
