    Wrker

    Wrapper around wrk for easier testing. Runs multiple times at different connection counts, averages multiple tests, graphs results, and more.

    Installation

    Wrker uses node. You'll need to install wrk and node before installing wrk:

    npm install -g wrk

    Usage

    Example

    wrker -i 100 -d 1 -a 3 -s 5 -r browser http://127.0.0.1:3000/

    • Run wrk for 100 iterations
      • for 1 second each
      • each iteration should be an average of three runs
    • stepping up by five connections each iteration
    • using the browser reporter
    • hitting the server http://127.0.0.1:3000/

    Full Guide

    Usage: wrker [options] <url...>
    
    Options:
    
      -h, --help                output usage information
      -V, --version             output the version number
      -v --verbose              Verbose mode
      -i --iterations <number>  The number of test iterations/increments to run (default 10)
      -d --duration <number>    The duration in seconds for each test (default 5)
      -a --averageOf <number>   The number of repeat tests to run at each stepping interval (default 3)
      -s --stepBy <number>      The number of concurrent connections to step up by each iteration (default 10)
      -r --reporter <value>     The reporter to use (defaults to console.) Use one of: 
    							  * csv
    							  * console
    							  * browser (experimental)
    

    Notes

    There are some rough edges:

    • I got lazy and haven't yet written tests
    • Parsing of wrk data which uses SI prefixes is not yet implemented
    • The browser reporter is currently pretty basic. It doesn't currently display a bunch of stuff you'd definitely want from graphs: scales/axes, item labels and counts, comparison scatterplots, overlay latency stats on the same graph, and much more. I'm getting to this.
