micro-benchmark


ES5 compatible, dependency-free benchmark suite.
Runs in node.js and in a browser (IE 9+).

Installation

``
npm install micro-benchmark
`

Example

`javascript
// node.js
var microBenchmark = require('micro-benchmark');

// node.js & browser
var N = 1e4;
var result = microBenchmark.suite({
duration: 100, // optional
maxOperations: 1000, // optional
specs: [{
name: 'sin(i)',
fn: function () {
for (var i = 0; i < N; ++i) Math.sin(i);
}
}, {
name: 'sqrt(i)',
fn: function () {
for (var i = 0; i < N; ++i) Math.sqrt(i);
}
}, {
name: 'pow(i, 2)',
fn: function () {
for (var i = 0; i < N; ++i) Math.pow(i, 2);
}
}]
});

var report = microBenchmark.report(result, { chartWidth: 10 / 30 is default / });
console.log(report);

// outputs
// Name Operations per second Average time, ms
// sqrt(i) 9.9 x 10^4 0.01 ==========>
// pow(i, 2) 9.6 x 10^4 0.01 =========>
// sin(i) 3.3 x 10^3 0.30 =>
