A simple benchmark tool for Node.js
npm install nodebench
Example code:
var NodeBench = require('nodebench'); // require this module or ...
//var NodeBench = require('./NodeBench.js'); // require main file directly
var NB = new NodeBench(); // output to console or ...
//var NB = new NodeBench('benchmark.log'); // output to file
NB.start();
NB.tick('the first tick'); // record this tick
NB.tick('the second tick'); // record this tick
NB.end();
NB.report();
The output might be:
