Note that there are a few things which cause AppleScript from MacPerl to be
slow.

1.  AppleScript is much slower than MacPerl at certain operations, like
text processing
2.  Apple events are slow (faster than they used to be, though)
3.  MacPerl compiling AppleScript takes time

The last one there can be alleviated some by either using Mac::Glue (which
is slower in startup time but can be much faster once it gets going,
because it does not need to compile the AppleScript), or Mac::OSA /
Mac::OSA::Simple, which allows you to compile an AppleScript (or any OSA
language for which a component is available) once and execute it many times.

Actual speed differences depend on a lot of factors, so whatever works for
you: do it.
