Robert,
Recursion in every language is going to be slow and is a bad practice
unless
you have no other way of implementing the code. ColdFusion does not
necessarily have a strong type for objects.. so its even going to be
slower.
If you have no other means.. i would suggest you write your recursive
funtions in Java.. plain old class...you will get scalabilty you are
looking for
and its easy to deploy it on CFMX
