Question

What is a good way to measure code execution time in VBScript?

Or failing that how to do it in JavaScript?

Answer 1

For VBScript you can use Timer:

StartTime = Timer()
EndTime = Timer()
Response.Write("Seconds to 2 decimal places: " & FormatNumber(EndTime - StartTime, 2))

Or ASP Profiler (that is for an ASP environment.)

For JavaScript you can use Date:

var start = new Date().getTime()
alert("Milliseconds: " + (new Date().getTime() - start))

Firebug also has a profiler for JavaScript.
