I get what you are saying, I was agreeing with you. :)

We *were* writing all of our AGI as binary executables and even then, 
the FastAGI server that we eventually built still gets better 
performance vs. when we launched separate AGI per call from the 
dialplan.  My guess is that it is easier on the system for an existing 
executable (FastAGI Server) to spawn threads of execution for short 
periods of time to handle (Fasg)AGI requests than it is to run separate 
executable AGI's instead.  We're hoping that performance will be 
improved even more when we introduce pooling of common objects (db 
access for example).
