[Freeswitch-users] Max of 170 channels in the conference room.

The conference is more resource intensive than normal bridging but the
general rule for media channels is about 190 channels (95 bridges) per 1
gigahertz of CPU on a 64 bit platform.  If you don't need to run media into
FS you can bet on a lot more.
