There are certainly sufficient changes in the performance characteristics of some language features that what was "best practice" in terms of performance for CF5 will not necessarily be "best practice" for CFMX. Perhaps the mot fundamental example is custom tags - in CFMX, these are pretty much as fast as using a UDF (or the new CFC feature). Code that went out of its way to simulate custom tag behavior in a 'faster' way will probably be slower on CFMX (Matt Liotta can probably comment on this). The Coding Guidelines published on my site (see the "ColdFusion Resources" page at http://www.corfield.org/coldfusion/) contain some performance tips that were originally true of CF5 with notes saying which have been validated on CFMX and which have not (lack of time on my part). That is not meant to be a definitive list, merely a few examples. The business of code optimization has always been fraught with version-specific issues but the bottom line is that simple code is usually faster. That is especially true in a compiled language environment where complex code can often prevent the compiler from doing a good job of optimization.
