javascript - video framerate problems with webrtc on socket -

i have made simple application webrtc using kurento media server. application server side written on nodejs , client side simple html.

the problem facing little weird.

for being able use webrtc functionalities using sockets (socketio) achieve functionalities.

when make socket object in same file server.js , use within same file, frame rate of videos seen on screen perfect:

server.js

var app = express(); var server;  var server = app.listen(port, function () {     console.log('app started'); });  var io = require('socket.io')(server);  io.on('connection', function (socket) {     socket.emit('id', socket.id);      socket.on('error', function (data) {     });      socket.on('disconnect', function (data) {     });      socket.on('message', function (message) {     }); }); 

in above case, frame rate of video stable @ 30fps when send or receive streams.

but when make separate file handle socket messages, application seems go slower , video frame rate drops 15-20 fps:

server.js

var app = express(); var server;  var server = app.listen(port, function () {     console.log('app started'); });  var io = require('socket.io')(server); require('./sockethandler')(io); 

sockethandler.js

module.exports = function(io) {     io.on('connection', function (socket) {         socket.emit('id', socket.id);          socket.on('error', function (data) {             });         });          socket.on('disconnect', function (data) {         });          socket.on('message', function (message) {          });     }); } 

it seems passing reference of socket object server.js sockethandler.js seems causing application level problems. have solution this??
