[Freeswitch-users] Load testing and thread use

[Anthony Minessale]

The core philosophy of the entire design is based on a single thread per
channel.
There is no way to avoid this.

What are the specs of your machines?
DId you try using the 2003 server instead of XP (a home version meant for
single users)

We have little feedback on performance on win32 (good or bad) but we do have
many people using it.

Did you do any more extensive profiling to see what is using the most cpu
(look for process explorer)
