Hangup of sending Socket.io to NODE under Windows - how to treat?

Good afternoon. I looked all over the Internet - I did not find the answer. There is a socket.io library for node. On linux it works as expected. But I work in windows (or rather, I study). And there is a small bug there. Not only is transport defined not as a websocket but as pooling, but this is not the problem. The problem is that when more than 1 client connects, sending messages via socket.io freezes for 10-20 seconds, and if you send it again, the new and previous ones pass instantly... Do you know this situation and if so, how to treat it?
my Server:

var io = require('socket.io');
var http = require('http');
var fs = require('fs');

var app = http .createServer(handler);
var io = io.listen(app);
app.listen('80');

function handler (req, res) {
  fs.readFile(__dirname + '/index.html',
  function (err, data) {
    if (err) {
      res.writeHead(500);
      return res.end('Error loading index.html');
    }

    res.writeHead(200);
    res.end(data);
  });
}

io.sockets.on('connection', function (socket) {
  socket.on('eventtoServer', function (data) {
    console.log(data);
    io.sockets.emit('eventtoClient', { data: data.msg });
  });
  socket.on('disconnect', function () {
    console.log('user disconnected');
  });
});

my client:

<html>
<head>
  <title>Test socket.io</title>
  <script src="/socket.io/socket.io.js"></script>
  <script>
  var socket = io.connect('http://200.14.1.124:80');

  socket.on('eventtoClient', function (data) {
    document.getElementById("name").value = data.data;
    console.log(data);
  });
function send(){
var msgfromclient = document.getElementById("inp").value;
  socket.emit('eventtoServer', { msg: msgfromclient });
};

  </script>
</head>
<body>
  <textarea id="name" rows="8" cols="40"></textarea>
  <p></p>
  <input type="text" name="text" id="inp" size="20">
  <button type="button" name="button" onclick="send()">Отправить</button>
</body>
</html>

ps. Win10 system, on winServer12 the behavior is the same.

You need to specify the socket type in the options.
const io = require('socket.io')(httpServer, { wsEngine: 'ws' });
This problem is only on Windows. Therefore, in the new version of socket.io 2.1.0, this setting will be the default.
