Idea

benchmarx automates your benchmark running/reporting, and supports ab, siege, and slam (a pure-node alternative).

Benchmark a server (implement a listen() method) or a middleware (implement a middleware method), and easily create side-by-side reports by adding new files to your bench folder.

Setup

  1. npm install --save-dev benchmarx in your project folder
  2. Create one or more benchmark files (format described below), and put them in a bench or benchmarks folder
  3. Add a Makefile such as this
  4. Type make bench!

API

(see examples here)

A benchmark file is a Node module which should export the following:

Property: name (optional)

The name of the module/benchmark (for reporting). If not specified, the file's basename will be used.

Property: version (optional)

The version of the module/benchmark. If not specified, benchmarx will attempt to find the version automatically (by finding a package.json for the module called name)

Method: middleware(options)

If you're benchmarking a middleware, have this function return your middleware function.

Options passed to this function come from benchmarx --opts <path> (path to a JSON file containing options).

Example

exports.middleware = function (options) {
  return require('buffet')(options.root, {watch: false});
};

Method: listen(options, cb)

If you're benchmarking a server, have this function call cb(err, port) or cb(err, "host:port") to tell benchmarx which port the server is listening on.

Example

exports.listen = function (options, cb) {
  var server = require('http').createServer(function (req, res) {
    res.end('hello world!');
  });
  server.listen(0, function () {
    cb(null, server.address().port);
  });
};

Method: close()

If you're benchmarking a server, this function will be called once benchmarx is done, so you can clean up your stuff.

Example

exports.close = function () {
  server.close();
};

Usage


  Usage: benchmarx.js [options] [files...]

  Options:

    -h, --help                 output usage information
    -V, --version              output the version number
    -r, --runner <runner>      choose slam, ab, or siege (default: slam)
    -c, --concurrency <num>    level of concurrency (default: 10)
    -t, --time <seconds>       length of each benchmark (default: 30)
    -w, --wait <seconds>       wait between benchmarks (default: 10)
    -p, --path <path(s)/file>  URL path(s) to test, can be comma-separated, or newline-separated file (default: /)
    --opts <path>              file path to a JSON file to load options (passed to benchmarks)
    -o, --out <outfile>        write results to a file
    --title <title>            title for the header
    --no-random                disable random benchmark order
