[Freeswitch-users] Apparent performance bottleneck and FS freeze

Is that the only ones? how frequent are they?  Those are only for
expiration and run very infrequently.  You may wish to study it longer
because that should not be enough to slow everything down.  Your server is
not on a fake HDD too is it?

I generally do not help on load testing or virtual server setups because it
can consume a lot of time.
