[Freeswitch-users] high pdd

Thu Aug 21 01:26:08 MSD 2014

The cond waits are all of your session threads in bypass media mode asleep
in the state machine.
Its hard to tell with that blurry screen shot what else is going on.  Is
there a way to produce that data in a way we could browse it?

You should be looking for threads in the sofia sip stack and the ones doing
originate if you are worried about pdd.  Also which threads are costing the
most CPU.  If conditionals are implemented in windows as
waitforsingleobject i have no idea if that's as efficient as it is in linux.

You could try forklifting in our modified copy of APR that has been updated
to work with their latest release and see if anything has improved in the
windows implementations of conditionals.  I recall Jeff had to backport in
at least one patch for that over the years.
