ben

Benchmark synchronous and asynchronous snippets simply.

examples

synchronous

var ben = require('ben');
 
var ms = ben(function () {
    JSON.parse('[1,2,3]')
});
 
console.log(ms + ' milliseconds per iteration');

output:

0.0024 milliseconds per iteration

asynchronous

var ben = require('ben');
 
var test = function (done) {
    setTimeout(done, 10);
};
 
ben.async(test, function (ms) {
    console.log(ms + ' milliseconds per iteration');
});

output:

10.39 milliseconds per iteration

methods

ben(times=10000, testFn)

Return how many milliseconds it takes to execute testFn.

testFn will be executed times many times.

alias: ben.sync()

ben.async(times=100, testFn, cb)

Compute how many milliseconds it takes to complete the asynchronous function testFn. testFn(done) will be called with a done callback to move along to the next iteration.

After testFn is run times many times, cb will be called with the number of milliseconds on average that testFn took to finish.

install

With npm, do:

npm install ben
