Question

As some of you probably noticed jsperf is down for some time. But I still need to profile my Javascripts. Is there any possibility to do comparison tests ideally without the help of an external software?

I decided to build tool like this. First public beta is at

jsperf is based on benchmarkjs so using an online code editor (like jsfiddle, jsbin, plunker etc...) and including benchmarkjs as a library will do.

The only feature you won't have will be the compiled results for each browsers. This is just a temporary alternative.

Here is a jsfiddle template :

But since we don't really care about HTML nor CSS I found plunker more suitable. Coupled with systemjs you can then separate your code into multiple files.

Here is the template :

You really should only use those solution as quick temporary solution. As said on the comments for optimal result you had better run it locally, nowadays you can get a webserver like express or else running in sec.

Rather than "trick" Stack Overflow into allowing posting of these links, let's actually include some helpful code:

function test1() {

}

function test2() {

}

var cycleResults = document.getElementById('cycleResults');
var result = document.getElementById('result');
var btn = document.getElementById('btn');

// BENCHMARK ====================
btn.onclick = function runTests() {

  btn.setAttribute('disable', true);
  cycleResults.innerHTML = '';
  result.textContent = 'Tests running...';

  var suite = new Benchmark.Suite;

  // add tests
  suite
    .add('test1', test1)
    .add('test2', test2)
    // add listeners
    .on('cycle', function(event) {
      var result = document.createElement('li');
      result.textContent = String(event.target);

      document.getElementById('cycleResults')
        .appendChild(result);
    })
    .on('complete', function() {
      result.textContent = 'Fastest is ' + this.filter('fastest').pluck('name');
      btn.setAttribute('disable', false);
    })
    // run async
    .run({
      'async': true
    });
};

<script src=""></script>
<ul id='cycleResults'>

</ul>
<div id="result">

</div>
<br>
<button id="btn">
Run Tests
</button>

Answer 3

There is also which allows you to create and run javascript benchmarks

Answer 4

I have incidentally come to know .

It clearly reminds of good ol' jsperf.

You can save your benchmark, share them and they keep track of per-browser performance.

Here is one I just made up: For loop benchmark

(As a side note, you can only save a benchmark if you have a github account.)

Answer 5

Even though jsperf is online, if you still want to look at alternatives, I found to be quite useful and well designed.
