Timing JavaScript execution with Fiddler

I have been doing some performance debug work with fiddler recently and I wanted to add some timers to the java script which I am debugging via using an auto responder.

For the JavaScript I am interested in I added the function below at the top of the script.

function now()
{
var d = new Date();
return (d.getTime());
}

At the beginning of the function I want to time I added

var time = now();

At the end of the function I added

alert(“Time to execute = ” + (now()-time)+”);
