[Freeswitch-users] help with mod_conference stability

[Stephen Crosby]

Thanks Pete,

I've been hanging out on #freeswitch and I started a conversation on this
topic. User 'mercutioviz' created this wiki page mercutioviz:
http://wiki.freeswitch.org/wiki/Which_scripting_language_should_I_use%3F

which should help new freeswitchers not make the mistake we made and have to
rewrite everything. If you have anything to add to this, it would be
appreciated I'm sure.

only thing I need JS for at this time is cURL-like calls, as the built-in
LUA has no equivalent to the JS Socket object.  Having said that, the built
in LUA can take advantage of LUA libraries that are installed on the OS, and
LUA socket libraries do exists, so it is just a matter of me getting the
time to install them.

I'd love to see some data that shows how big the difference really is. I
could port all my scripts from javascript to lua, but it would require a lot
of overhead (me learning lua + actually porting the scripts). I want to know
how much benefit there really is to that.
