>From what I gleaned from Michael Dinowitz's excellent article on comparisons
(I can probably find the link if you like) recently, the first would be
faster because CF takes one less step:
(ignoring the Trim() because it affects both examples equally)
<CFIF Len(newpassword)>
1) Evaluate the length of the passed string.
2) Does a very fast boolean evaluation of the length. If the number is 0
then the expression if false, otherwise it is true.
<CFIF newpassword IS "">
1) Evaluate newpassword
2) Evaluate the other operand, which in this case is ""
3) Compare the two using a string comparison
Not only does the first method force CF to take one less step, but the
evaluation of the length as a boolean is a faster operation than comparing
two strings.
