The functional behavior will be the same. Performance, OTOH, will
depend on a number of factors.

The optimisations the compiler will be able to perform will vary across
systems.

It's platform specific. On OS X, structKeyExists() is always 20-30%
faster under any circumstances. On Windows isDefined() is often
faster.

CF is certified on some versions of WebSphere, WebSphere uses IBMs JVM
so by extension CF works. Don't know about JRun though.

It's not so much ColdFusion's performance as the unde

In 6.1 I can't see a difference for application scope.
Of course there is a difference between
IsDefined("attributes.MyVar")
And
structKeyExists(attributes, "MyVar")
As the attributes scope doesn't always exist.

I've gotten into the structKeyExists() habit.

It also depends on the name of the variable
Take for example a variable named "_data"
You cannot do:
I know in previous versions they were different. Seems logical to me that
they should work the same in MX since scopes are just regular structures.
