Offhand, I'd think REFind() would be faster than REFindNoCase(), since
neither the string being tested, nor the RE would have to transformed to all
caps (or all lowercase) prior to the test.
If I've got an RE that already takes into account case insensitiviy by using
character classes, which function would be faster? For example, an regex
such as:
<cfset re =
"^([[:alnum:]-]+\.)*[[:alnum:]]+(-*[[:alnum:]])*\.[[:alpha:]]{2,}$">
