Actually 'NOT Len(variable)' would theoretically run faster than
Len(variable) EQ 0 ... Here's another tip for you. Cold Fusion can handle
any integer as a Boolean value (see the IsBoolean function) with any non
zero integer being true, and any zeros being false. So by using the NOT
operator you can evaluate the result of the Len() function as a Boolean,
because in this case you don't care what the Length of the string is, as
long as it isn't zero. If you wanted to test if a string isn't empty (a
True return, or non zero return, of the Len() function) then you can just
say...
<cfif Len(variable)>
There are a couple resources out there...

We also have some resources on CFDEV.COM

I would love to make a definitive list of this stuff, We would be happy to
host it on CFDEV.COM if anyone is interested in helping me compile a list

Subject: Ways to improve performance?
Every now and then someone posts code and explains that such-and-such runs
faster than something else because -----. Is there a list of all of these
ways to improve code performance?
I know about using CFLOOP instead of looping through CFSCRIPT and that
Len(variable) EQ 0 is faster than variable EQ "".
Thanks.
Ian
