micro-benchmark

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

Installation

npm install micro-benchmark

Example

// 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                =========>

function profile(fn, config)

• fn - function to profile
• config - {{ maxOperations: number, duration: number }}, optional
  • maxOperations - optional function execution number limit, default value is 1000
  • duration - optional time limit, default is 100 ms

function profileAsync(fn, config, cb)

• fn - function to profile, should call it's first argument: next()
• config - {{ maxOperations: number, duration: number }}, optional
  • maxOperations - optional function execution number limit, default value is 1000
  • duration - optional time limit, default is 100 ms
• cb - callback function

function suite(config)

• config - {{ specs: [], maxOperations: number, duration: number }}, optional
  • specs: array of objects {{ name: string, fn: function }}
  • maxOperations - optional function execution number limit, default value is 1000
  • duration - optional time limit, default is 100 ms

function suiteAsync(config, cb)

• config - {{ specs: [], maxOperations: number, duration: number }}, optional
  • specs: array of objects {{ name: string, fn: function }}
  • maxOperations - optional function execution number limit, default value is 1000
  • duration - optional time limit, default is 100 ms
• cb -- callback function

function report(suiteResult, config)

• suiteResult - result of suite(...)
• config - {{ chartWidth: number }}, optional
