node-benchmark

a benchmark util for Node.js.
You can use it test every function, get a report like this:

Benchmark test at Fri Sep 07 2012 01:53:53 GMT+0800 (CST):
getAsync(123, cb)
Number of totaol request: 1000, CONCURRENT users: 10

Usage:

• Use nbm:

 nbm [options]
example:./benchmark -c conf.js -l out.log -t md

Options:
  -c, --config   input config file path, array of inputs       [required]
  -l, --log      -l FILE, LOG to FILE.                       
  -t, --logType  log type, could be markdown/md, default text

• In conf.js, must exports a array of options. These options are for lib/benchmark:

var rewire = require('rewire');
var methods = rewire('./example/methods');
/**
 * {Number}   requests      total requests number
 * {Number}   concurrent    concurrent user number
 * {String}   type          which type of method, `sync`, `async`, `http`, `hsf`
 * {Function} method        which method want to be test
 * {Array}    args          invoke arguments
 * {All}      result        expect invoke result
 * {String}   description   describe this method, just for dispaly and record to the log file
 * @type {Array}
 */
module.exports = [{
  requests: 10000,
  concurrent: 500,
  type: 'async',
  method: methods.getAsync,
  args: [123],
  result: 123,
  description: 'getAsync(123, cb)'  
}, {
  requests: 10000,
  concurrent: 500,
  type: 'async',
  method: methods.__get__('_privateGet'),
  args: [123],
  result: 123,
  description: '_privateGet(123, cb)'  
}];

Just like upside, use rewire can get the private method to be tested.

Install

npm install -g node-benchmark

Todo

• more test
• sync, http, hsf method support
• api
