如何获得asp页面的载入时间

<!--- 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"

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;
}
