I have to say, I fully agree with Sean here, and disagree with you. If ANYONE uses one million of ANYTHING in a single program, that person has bigger problems than optimization choices. CF is simply not the appropriate platform for a million operations of anything in a single program. That's not what it's for. If you have those kind of requirements, use something else - Java comes to mind - and invoke it from CF. A completely unrealistic test tells you how to optimize for completely unrealistic environments. What's more, the optimization won't apply universally to similar unrealistic environments in the future, because the internals of CF (and other CFML interpreters/compilers) change frequently enough to make your optimization choice fail in other versions.
