Node.JS Benchmarks
==================

[![NPM](https://nodei.co/npm/benchmarks.png?downloads=true)](https://nodei.co/npm/benchmarks/)

Javascript is a non-opinionated language and allows you to do an operation in many ways.
This repository tries to find which approach is faster in a range of different systems.

Installation
------------

    $ npm install -g benchmarks

Usage
-----

    $ node-benchmarks --help
    Usage: node-benchmarks [options]
    Options:
        -h, --help         output usage information
        -V, --version      output the version number
        -p, --path [path]  Path to output the results to
        -d, --dryrun       Run the benchmark but dont generate files

    $ node-benchmarks -p myresults/
    [1/21]  type_check
    [2/21]  send_buf
    [3/21]  manip_recv_buf
    [4/21]  duplicate
    [5/21]  object_loop
    [6/21]  bluebird_vs_q
    [7/21]  array_filter
    [8/21]  conditional
    [9/21]  array_prepend
    [10/21] buf_write
    [11/21] delete
    [12/21] inc_int
    [13/21] function_call
    [14/21] proto_vs_literal
    [15/21] delete_last_item
    [16/21] array_map
    [17/21] string_search
    [18/21] buf_read
    [19/21] round_num
    [20/21] array_loop
    [21/21] str_to_int

Your benchmark results will be appended to the result set.

    $ node-benchmarks --dryrun
    typeof x 22,545,486 ops/sec ±11.66% (30 runs sampled)
    constructor check x 18,023,021 ops/sec ±9.23% (27 runs sampled)
    Fastest is typeof

    [1/22]  type_check
    buffer x 10,889 ops/sec ±15.81% (28 runs sampled)
    string+ x 53,569 ops/sec ±21.72% (27 runs sampled)
    Fastest is string+

    [2/22]  manip_recv_buf
    filterDuplicates x 17,466 ops/sec ±7.64% (26 runs sampled)
    eliminateDuplicates x 19,910 ops/sec ±7.11% (28 runs sampled)
    Fastest is eliminateDuplicates

When `--dryrun` is used, no files are generated and the results are shown on the console.
