Hi Giuseppe,

have you already looked to the "benchmark" module? It can be used to create 
arbitrary timers in the configuration file. If you need to have it per request 
and response, you probably could just include the sending time in a special 
message header in the sent out request. They are several pseudo-variables 
available which contains timestamps in different formats.

If you want to benchmark the complete server, an external probe should be the 
way to go. Just send test requests e.g. with sipp, it can also output the 
response time.

Cheers,

Henning
