jsPerf.app is an online JavaScript performance benchmark test runner & jsperf.com mirror. It is a complete rewrite in homage to the once excellent jsperf.com now with hopefully a more modern & maintainable codebase.
jsperf.com URLs are mirrored at the same path, e.g:
https://jsperf.com/negative-modulo/2
Can be accessed at:
https://jsperf.app/negative-modulo/2
<div id="wrapper">
</div>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">

$(function(){
for (var i = 0; i < 1000; ++i) {
if (i == 501) {
$('#wrapper').append('\
<div id="container"><ul>\
<li>1</li>\
<li class="target">2</li>\
<li>3</li>\
