I have no idea if wrapping the entire request in a CFTRY..CFCATCH will slow
down the request. In fact, I don't even care, unless app performace becomes
a problem, and I've spent time optimizing the rest of the system
(particularly the DB). IMHO, you should NEVER make high-level architecture
decisions based on performace. Design the system as well as possible from
an architecture standpoint. Experience shows that good architecture usually
leads to good performance, and the places that it doesn't are usually
because the need for maintainability or abstraction were more important than
raw speed. Six months down the road, it's a lot easier to do optimization
than rearchitecting, so put them in the right order on the priorities list
up front.

In FB4's case, if you've got a exception handling plugin, you're entire
parse file is wrapped in a CFTRY..CFCATCH anyway, so adding one to index.cfm
isn't going to matter much. The only different will be the runtime core,
which is quite trivial (the vast majority of the core code is in the other
three files).
