async_bench v0.5.1

The benchmark framework designed for node.js callbacks.

async_bench

BuildStatus

The node.js benchmark framework designed around the node callback style.

Installation

npm install async_bench --save

Example

var bench = require("async_bench");
var crypto = require("crypto");
var fs = require("fs");

bench({
  runs: 10000,
  preHeat: 10000,
  setup: function(cb) {
    fs.readFile(__filename, cb);
  },
  bench: function(data, cb) { 
    var shasum = crypto.createHash('sha1');
    shasum.update(data);
    var d = shasum.digest('hex');
    cb();
  },
  complete: function(err, results) {
    if (err)
      throw err;

    console.log(results);
  }
});

Motives

In node, the most popular style for passing callback is:

myAsyncFunction(function (err, arg1, arg2, ...) {
  // do something
});

Where the first argument is the error. async_bench is the first benchmark library that adopted this style.

In async_bench all steps are defined using this convention, and everything is run by the popular async library.

Contributing to async_bench

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
  • Fork the project
  • Start a feature/bugfix branch
  • Commit and push until you are happy with your contribution
  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
  • Please try not to mess with the Makefile and package.json. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
