Two side points:
1. I don't think cfincluding a file with many function definitions would
have a measurable impact on performance. In fact, I did a test (4.5sp1
Linux) to compare 40 cfset's to the Request scope, versus doing the
appropriate Application-scope locking and conditionally doing 40 cfset's to
the Application scope. I could not measure statistically significant
(greater than 0.1%) difference in performance for 1000 iterations.
2. The "Trusted Cache" option in the Administrator (which is what I think
you're referring to) doesn't really have any impact on performance, unless
you're reading your CFM files from a network share. ColdFusion will always
cache the "compiled" version of a template, unless the Template Cache Size
is too small, in which case you'll start seeing Cache Pops in NT Performance
Monitor or cfstat. The Trusted Cache option tells CF to /not/ check the
time/date stamp on the CFM files accessed, to see if they've been updated.
If the files are on a HDD that is local to CF, then the performance impact
is negligible. My recommendations: make the template cache size [ceiling]
10x larger than all your code. CF does not preallocate that memory. Also,
leave "Trusted Cache" /off/ unless CF is reading the CFM files over a
network share. (Otherwise the inconvenience of having to restart CF every
time you push new code is far larger than the benefit of not rechecking the
date stamps.)

Neat idea, but do you really think cfincluding them, perhaps in the
Application.cfm page, would be that heavy? If you turn on Template Caching
in the CF admin, all templates will be cached in RAM, and I would think
that would serve the same purpose and be a bit simpler to implement. I'd
be interested in seeing some performance stats on both methods.
