Hi Nat,
I was wondering about this, after the talk that Ben Forta gave at the conference in DC
this past summer about optimize CF server where he recommended not over-using
<CFOUTPUT> because if forces CFAP to parse every single line.
I was wondering if <CFOUTPUT> really matters at all once the page is put into p-code
in cached memory. If the parsing is only done once at cache time, it probably does
not matter at all.
Any thoughts on this?
