asterisk users - Jun 2006 - ExternalIVR vs AGI

I have an Perl AGI script that acts as an IVR for my Asterisk box.  
Basically, it simply plays audio files to the caller, collecting DTMF  
input and logging every DTMF input into a database table, simply to  
document every step or option selected by the caller.

One thing is that in addition to playing audio files, it also, at  
some point, plays SayUnitTime command.

This IVR has constantly about 20 simultaneous callers 24x7.

Would it be more resource efficient to migrate this to ExternalIVR?  
What are the pros/cons of using ExternalIVR vs using my Perl AGI.

Thanks,
Daniel

Probably no difference. The ExternalIVR lets you interrupt actions  
(like playing a recording) where
the AGI will not. But you don't need that. If the caller hangs up  
early (say, in the middle of a playback),
I think both AGI and ExternalIVR quit immediately.
