    Visual Bench

    Synopsis

    Visual Bench sits on top of bench and it has a dual purpose:

    • Automatically save the benchmarks into a data file in JSON format
    • Allow the results to be visualized in a web browser

    Installation

    npm install visualbench -g

    Usage

    Generating some data

    Load the module and supply an id to use as a data key, and optionally a file where to store the data.

    var bench = require('visualbench')('emit:0.0.4')

    Showing the data

    Start the server with vbserver.

    For more options, run vbserver --help.

    For debugging, run DEBUG=http vbserver.

    Example

    First, generate some data.

    var bench = require('visualbench')('testId')
     
    // Straight from the `bench` examples
    var foo = 1
      , bar = 2
     
    function tmpvar () {
      var _ = foo
      foo = bar
      bar = _
    }
    function arrswap () {
      foo = [bar, bar = foo][0]
    }
    function fnswap () {
      (function(x,y){foo=x;bar=y})(bar,foo)
    }
     
    exports.compare =
      { tmpvar: tmpvar
      , arrswap: arrswap
      , fnswap: fnswap
      , "nil function":function () {}
      }
     
    bench.runMain()

    This will generate the data.json file, containing something similar to the following data.

    {
        "var-swap":
            {
                "tmpvar": [
                    117527.47252747252, 115553.44655344656, 113636.36363636363, 99736.26373626373, 98266.73326673327
                ]
            , "arrswap": [
                    60341.65834165834, 58489.51048951049, 57202.79720279721, 54672.32767232767, 53621.37862137862
                ]
            , "fnswap": [
                    55766.23376623377, 54548.45154845155, 51734.26573426573, 51650.34965034965, 51682.317682317684
                ]
            , "nil function": [
                    149618.38161838162, 149757.24275724276, 144548.45154845156, 127869.13086913087, 127647.35264735264
                ]
            }
    }

    Start the web server.

    vbserver

    Point your web browser at http://localhost:8080

    Enjoy the results!
