For question 3, the biggest difference is whether you can have CF processing in your files. Usually for config stuff, CF is not used, so either will work in this case. CFFILE does not have the overhead associated with the CFSAVECONTENT tag (minimal, but still there), nor the CFMX compilation cycle. However, CFFILE doesn't get the benefit of cached templates like the CFINCLUDE would from the CF server. Both will benefit from filesystem-level caching/buffers.
I suspect that CFFILE is faster than CFSAVECONTENT/CFINCLUDE because there is no processing overhead, but you'd have to do some tests to see if that's the case (loop over each one a few thousand times and use gettickcount() to see how long it takes). To get to the final point though, if it's a config file that's static, just read it once, and cache it somewhere (probably the parsed representation, rather than the raw data), and then the discussion is moot. cheers, barneyb --- Barney Boisvert, Senior Development Engineer AudienceCentral (formerly PIER System, Inc.)
