[Users] load testing presence server

[Toni Barata]

Hi Ovidiu,

Thanks for the tip. 

But using the asynchronous mode it was not enough to increase the presence server performance if debug parameter is >= 3.

Best Regards,
Toni

Hi Toni,

Maybe this will help you:
http://www.voice-system.ro/docs/ser-syslog/ar01s06.html
Check the Note at the end of the page:
NOTE: The '-' in front of "/var/log/ser.log" is to omit synchronizing
the log file after every log message. If you choose to configure
"syslog" in synchronous mode you must be aware that it has big impact
over performances when the signaling traffic is high.


Regards,
Ovidiu Sas
