I found this Javascript function and it seems to be working. If anybody finds any flaws in it, PLEASE let me know. I cant seem to find any.

<!-- This function computes the time it took to load up the page -->
<script language="JavaScript">
function results()
{
var time2, timed, thruput, title
time2 = new Date()
//Calc difference and convert from msec to sec.
timed = (time2.getTime()-time1.getTime()) / 1000
/* Calc Kbps using formula:
[throughput (in Kbps)] = [file size (in bytes)] * 8 / [elapsed time] / 1000

thruput = (225455 * 8) / timed / 1000
document.open() // Stops the page from loading.
document.close() // Turns off the hourglass.
title = "Speed Test - Graphics"
document.write("<html><meta http-equiv=Pragma content=no-cache><title>" + title + "</title>")
document.write("<body bgcolor=#FFFFFF>")
