Hello,
Please check, as Brett said, if your logging is not the issue - if
syslog is in async mode.
Further more, if logging turns out not to be the problem, you could use
the time threshold parameters from the core for DNS and overall message
processing [1], or the time threshold in the DB_MYSQL module, for
queries [2], to check if DNS or MySQL is causing this performance issues.

Hi all,
I'm running a sipp load test to an opensips instance on a 16 core,
8GB ram blade server. It's only 100 simultaneous calls, at 10
calls per second, and I'm getting lots of retransmissions from the
sipp UAC.
I'll give you the same advice I gave someone else just a sec ago.
Check your syslog config and see if you are set up for async writes.
Turn logging off completely on opensips and see if that changes
anything. I've seen bad logging configs bring perfectly capable
systems to it's knees.
