Hi, Rodrigo!

OpenSIPS by itself performs very well :). However, in a call, OpenSIPS 
is not all by itself: you need SIP clients, databases, DNS, and so forth 
and so on. In order to have better performance, you have to increase 
performance for each of these components. So you need to define what 
exactly is drawing OpenSIPS back: is it the processing itself, is it the 
database, is it the DNS and so on.

In order to pinpoint the components that have poor performance, OpenSIPS 
provides some thresholds that you can use to measure different stuff in 
the script, such as DNS queries[1], message processing [2] or mysql 
queries[3]. You should try to profile each of these and figure out what 
exactly is happening in your platform, to find out what exactly you 
can/should improve.
