[Freeswitch-users] Freeswitch performance issues

Sun Jul 21 15:57:21 MSD 2013

As Anthony said before, the most probable cause of poor performance is the
pretend server you are running on.

If you are absolutely certain there is a bug in freeswitch, then I would
advise doing the following;

* Purchase a cheap dedicated server from OVH
* Install Linux KVM
* Attempt to reproduce the problem

This will at least rule out the host machine being overloaded.
