Since when is CFLOOP "faster" then CFOUTPUT? I have seen on this list many,
many times that CFLOOP is one of the slowest tags in CF... I see your point
about not wanting to execute more code then is needed, but a lot of it
depends on what your doing. But in a show down between CFOUTPUT and CFLOOP,
I say that CFOUTPUT with a query attribute beats CFLOOP hands down every
day...

OK, there are 2 ways to look at this;
1) What's easier for you (and your team) to read and update
2) What's faster on then server when it's PCode
In answer to this, Listing 1 is always easier to read, but is slower on the
server
"Why?" you ask (sounds of "Why?" from all over the world)...
Here's how the CF Server looks at a template (if you don't have CFSetting
EnableCFOutputOnly="Yes" on);
It sends everything straight to the browser that's not a CF tag outside of a
CFOutput without even thinking, once it reaches a CFOutput it has to scan
through the code to find if anything requires any conversion from
function/variable/field contents into displayable values and then converts
those...
When you don't have any functions/variables/fields in the code, you're
effectively making CF work for nothing
Remeber that a file being larger in size (before PCode) means nothing to how
fast it might run on the server - it's the actual work that the server is
doing that's more important
If you wanted the best performance from a CFOutput query="" tag, then you
should use CFLoop query="" and only CFOutput the fields
Hope this helps explain why and why not to use CFOutput on everything
