You can do whatever you want, of course. I was just prioritizing by
ROI. God knows there are enough decisions made directly in the fact
of maximizing ROI.

Yeh, great explanation from barney.
I'd just like to add that, knowing this, the choice between if and
switch in CF is then down to readability / logic / personal
preference. If there is a conditional that has a single simple
expression with several 'options', switch reads far better to me.

Thanks for the suggestions Barney, Andy.
The unusual thing about this is that even Adobe's own CF8 ref docs do
mention about the better perfor
the webapper folks had an interesting blog post in the subject as well...

altho it seems that the issue they address was resolved in CF8.
still, an interesting read :)

That was a rumor a few years ago, because switch frequently performs
better in lower-level languages because of reduced expression
evaluation. I did some testing and found that the opposite is true in
CF: CFIF performs better than CFSWITCH. Not all conditionals can use
CFSWITCH, of course, but fo
I'm going to guess that switches, and ifs aren't going to be a bottleneck in
any of your code. If you're looking to improve performance you'd be best
starting at optimizing any of your queries first, then make sure all of your
variables are scoped inside CFCs, and the rest of your code, then make s
