Usage

Quick start

First of all, create a testing file, we called localhost.js, content below:

module.exports = {
  duration: '30s',
  connections: 400,
  threads:12,
  target: 'http://192.168.3.207:9200/listening_v3/sina_weibo/_search'
  // method: "GET",
  // stdout: false,
  // header: './header',
  // body: './post.body',
  /*
  onResponse: function  (res) {
    console.log(res.body);
  },
  */
  // report: function  (summary, latency, requests) { },
};

Then run the following command:

$ webench -c localhost.js

This runs a benchmark for 30 seconds, using 12 threads, and keeping 400 HTTP connections open.
