Benchmark

Use bench-rest (https://github.com/jeffbski/bench-rest/)

With config like this:

var benchrest = require('bench-rest');

var flow = {
  main: [
    { post: 'http://localhost:3000/s', json: {'url': 'http://mydata_kemal_#{INDEX}'} },
  ]
};
module.exports = flow;

benchrest(flow, { iterations: 10, limit: 100})
  .on('error', function (err, ctxName) { console.error('Failed in %s with err: ', ctxName, err); })
  .on('progress', function (stats, percent, concurrent, ips) {
    console.log('Progress: %s complete', percent);
   })
  .on('end', function (stats, errorCount) {
    console.log('error count: ', errorCount);
    console.log('stats', stats);
   });

With single polling: bench-rest -c 1 -n 100000 ./tubity.js

And concurrency: bench-rest -c 16 -n 100000 ./tubity.js
