Thanks for the input on this stuff guys, I think I can agree with you Chris, that was always my line of thought that cfscript is nearer to the runtime code and will need less parsing and compiling than the standard tag based code, I'd like to see some charted data on this stuff, Maybe I'll arrange something to be put together, perhaps some benchmark tests on core functions you'll find in many applications and then compare the two methods.
If I had the time I've always been curious to time functions across my entire application, having two versions, one running tagged code, the other running script, but to be honest, I'm not that sad :-D Thanks for your input guys, Rob -----Original Message----- From: Christopher Jordan [mailto:[EMAIL PROTECTED] Sent: 01 May 2007 14:16 To: CF-Talk Subject: Re: cfscript vs. cfml 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 Ben Nadel wrote: > I can't remember where I saw it, but someone actually looked at the > compiled code of CFScript vs. the compiles code of Tag based coding.
