Use local variables whenever possible. This not only aids maintenance by localising control, but also speeds up processing since the entire namespace does not have to be searched when the local variable is referenced. Also, copy individual collection values into local variables, if you are going to reference them a number of times (saves multiple lookups). Avoid redimming arrays. Instead, it's probably more efficient to declare the overall max size in advance.

ASP Coding for Performance - Dim Statements and Variable use
Declare a number of variables per line, using the Dim statement. This results in less lines to parse. e.g. replace
Dim sMyString
Dim sMyTemp
Dim iCounter
with:
Dim sMyString, sMyTemp, iCounter
