Streamline vs node with async call

node_bench.js

var net = require('net');

var start;
var socket = new net.Socket();
socket.connect(1111, 'localhost', function () {
  start = new Date();
  for (var i = 0; i <= 100000; i++) {
    writeByte(i);
  }
});

function writeByte (i) {
  socket.write(new Buffer([i]), function () {
    if (i === 100000) {
      var end = new Date();
      console.log("done: " + (end - start));
      socket.end();
    }
  });
}
