<!--- How can I time the execution speed of my ASP pages to the millisecond? --->
Doing this is easy with a simple server-side JavaScript function:
<script language=jscript runat=server>
function GetTime()
{
var d = new Date();
return d.getTime();
}
</script>
The getTime() method of the Date object in JScript returns the number of millisecond since Jan 1st, 1970. Therefore all you have to do it take a reading immediately before and after the process you are wanting to time. The following is an example, given that the above code it in GetTime.asp:
Dim StartTime, EndTime
StartTime = GetTime()
' Do some stuff here
EndTime = GetTime()
Response.Write "The process took: " & _
Cstr(EndTime-StartTimes) & "ms to execute"
If you want to see your process time in a better format, use the FormatMilliseconds function (created for the above timing script by www.learnasp.com):
function FormatMilliseconds(intMilliseconds)
{
var elapsedsecs = 0
ar elapsedmins = 0
elapsedsecs=Math.floor(intMilliseconds/1000);
intMilliseconds=intMilliseconds%1000;
elapsedmins=Math.floor(elapsedsecs/60)
elapsedsecs=elapsedsecs%60;
elapsedpretty=elapsedmins + " minute";
if(elapsedmins!=1)
elapsedpretty=elapsedpretty+"s";
elapsedpretty = elapsedpretty+" " + elapsedsecs+" second";
if(elapsedsecs!=1)
elapsedpretty=elapsedpretty+"s";
elapsedpretty = elapsedpretty+ " " +
intMilliseconds+" millisecond";
if(intMilliseconds!=1)
elapsedpretty=elapsedpretty+"s";
return elapsedpretty;
}
