AGIs do not have a substantial "performance hit" and I think people need to get this misconception out of their heads. Writing AGIs in a scripting, non-compiled language may be great for prototyping and proving concepts where performance is not expected to be an issue. Personally, I don't write AGIs in anything but C. It's the sharpest tool in my kit and I know it best. A lowly 1.6GHz Celeron can execute over 100 AGIs per second. I strongly suspect that the "startup hit" will pale to the "interpretation hit" of the dialplan script quickly. AGIs are a wonderful resource. You get the execution speed of an application (minus the usually insignificant startup hit) in a "sandbox" environment where you can't crash Asterisk and debugging is a couple of orders of magnitude easier. You can even write multi-threaded AGIs if needed. If you don't need to access the internals of Asterisk an AGI beats an application in my book. Maybe I should write one... I guess some day I'm going to have to cobble up one of my 2,000 line AGIs (written in C) in "dialplan" so I can speak with authority from actual experience. However, the absence of facts has never stopped me from expressing an opinion :) It seems that "compartmentalizing" a boat load of complex code in "a real language" (ducking quickly out of Tilghman's death glare) to be so natural to me for so many reasons I don't know where to start. So I won't.
