[KCFusion] include vs custom tag

[Dunwiddie, Bruce]

Title: include vs custom tag

We're still using cf 4.5 sp2. We're currently having a disagreement about whether to define our new framework for a site based on custom tags for each page basically, or the same thing using includes instead. I personally think the custom tags are a complete necessity, because of variable scoping, but I need to know the true benchmarking difference that people have seen when using one vs the other, or just in a per call difference in milliseconds per call, if anyone happens to know it or can point me to somewhere with the stats.
