Hello,<br>
<br>
Please check, as Brett said, if your logging is not the issue - if
syslog is in async mode.<br>
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.<br>

Hi all,<br>
<br>
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.<br>

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.<br>
