[Freeswitch-users] mod_conference scalability

Fri Dec 18 11:55:38 PST 2009

Brian, there was not one insulting word in anything I have said and as this
is a community mailing list my replies are always voiced to address the
public in general not you specifically, like I already mentioned in my last
post.

If you open a public forum on a FAQ be prepared to hear our policy.

Indeed many people do unrealistic load testing and most people with strong
will find it insulting when a group of people have a set of standard policy
by which they try to deal with making a penny jar for all the 2 cents worth
of input we get on a daily basis.  I can't begin to iterate over all the
cases we endure on a weekly basis.

additionally 90% of bug reports are on older releases and we always make
people reproduce their issues on SVN trunk because 3 core devs and a handful
of helpers can't maintain 20 versions of the code.

I gave you some really suggestions yesterday let me repaste it, I fail to
see any insults:

---------------------------------------------------------------------------------------------------------------------------------------------------
What exactly is your test process?

you should try increasing the interval in the conference profile to a bigger
time slice maybe 30 40 or 60ms
you could also increase the ptime to match as well.

like brian said you could use mod_shout to broadcast the single speaker to
icecast and let people listen with itunes/winamp

---------------------------------------------------------------------------------------------------------------------------------------------------

I have to get in these "fights" with people constantly so I guess that is
part of my job and my biggest mistake is spending so much time trying to
explain myself.
