In the universe of possible configurations...

This is our 'slow period,' but on my hardware, handling my application, at 
this moment in time, one of my hosts is handling 98 calls, has (as 
reported by 'top -d 30') a load average of 0.79, and CPU utilization of 
2.3% user and 8.9% system. Asterisk is using 85m of virtual memory and has 
35m resident.

I've seen 300 calls on the same host, but that was not a limit of the 
host, just how many callers were using the service at that point in time.

Note that my application (free chat rooms) is probably more resource 
intensive than your undisclosed application because all the frames from 
the participants have to be mixed with voodoo magic in the Zaptel driver.

Also note that my application uses a bunch of AGIs. Each call invokes at 
least 6 AGIs -- all requiring access to a MySQL database. All the AGIs are 
written in C.

If you can draw any conclusions from the above and relate it to your 
application -- congratulations :)
