A guy in my CFUG did a comparison of the decompiled JIT code, and found
that cfscript was faster. Sure if your example is:
<cfif (a eq b)>
<cfset a = c />
</cfif>
vs.
<cfscript>
if (a eq b) { a = c; }
</cfscript>
.... then the difference is likely to be immeasurable, but for more
complicated code that's not the case. Here's part of a post to my local
CFUG's mailing list on the subject:
"Obviously, ColdFusion is middle ware for your middle ware. It is a
collection of servlets that consolidate Java functionality into one
tidy command. Calling a tag when you can script it out with one
cfscript block, simply creates another import and more code in the
final JIT. If you write the code in cfscript, it is closer to the end
result (Java) than if CF has to import more servlet libraries to get
to the final result.
Get yourself a java decompiler, write the code both ways in two
different files, decompile the JIT, and you'll see what I mean."
Does any of this mean that I stopped using CF tags altogether? No. But I
use CFScript where I can, and where I think it will make a difference.
Just some more food for thought on this "age old" debate. :o)
Cheers,
Chris
