in the tests i've run, the cost of encapsulation with custom tags is too
high to make it a part of every template's execution.  custom tags are handy
when used for very specialized tasks, but should be avoided whenever
possible.  this is most important when tempted to use custom tags that use a
closing tag.  the penalties for these types are quite large and actually
grow with the size of the generated content between them.

you'll notice that using a custom tag with a closing tag increases the
execution ten-times that of using a cfinclude.  that being said though, this
particular problem isn't one that needs to be solved server-side.  it can
just as easily be solved with javascript and/or css.  therefore, this is a
perfect example of looking at the performance hit of the custom tag and
opting not to go with it as it's clearly not the best solution.

thanks,
