Note that if you run the CF8 debugger with break on exceptions enabled, you'll see it tries to convert strings to numbers in <cfif> as well in a lot of situations. This is kind of inherent in dynamic languages - and why some people use compare() or compareNoCase() for strings (but I think that's horribly ugly an unreadable). > I ran the same test code on our new CF8 server and was very happy to see > the switch was only about twice as slow for string values (and the same > for number values).

Which is why this sort of optimization concern is so pointless! :) Readability and maintainability are very important. Saving a millisecond here and there in a web-based application is pretty worthless since network latency and other issues tend to completely swamp any miniscule code savings you might make using <cfif> instead of <cfswitch>. And as we've seen repeatedly, what's faster in one release of one CFML engine is slower in another release or another engine... For example, Railo is faster at locating unscoped variables but slower as locating scoped variables - which is the opposite to ColdFusion!
