[Asterisk-Users] Performance testing of asterisk

[Tom Masterson]

What we are finding is that things work quite well with a small number of 
users/agents and callers i.e 10 or less.  However when we put the stuff in 
production (normally changes to the configurations) where they can and are 
hit with hundreds of callers among some 60 or 70 agents we have major 
failures.  What we are trying to do is come up with some automated way of 
creating the same effect so we can test changes before they go out to the 
rest of the group.  The generator does not have to be the same box as the 
test asterisk box but we need to recreate the scenarios as much as 
possible.

Any ideas?  I agree with Chris but it might still be better than nothing.
