Super simple example of adding perf timing to the page display during dev work
(function () {
var perfBar = function(budget) {
window.onload = function() {
window.performance = window.performance || window.mozPerformance || window.msPerformance || window.webkitPerformance || {};
var timing = window.performance.timing,
now = new Date().getTime(),
output, loadTime;
