Openshift runs my connect(); and disconnect(); functions too late - json

Question

I deployed my 7mb app into openshift and heroku. It works fine on heroku but on openshift it takes almost 2 minutes to run my io.sockets.on('connection', function(socket){}); and socket.on('disconnect', function () {}); functions(Other socket functions run fast enough). This causes huge problems because I use setTimeFout function in my code.
Note: While pushing my files to openshift I used to get
" openshift failed to execute 'control start' node-modules/bin/express
"
error. So I deleted express file at "myapp/node-modules/bin/express" and it worked.
Versions:
ruby: 1.9.3p0
node: 5.3.0
socket.io: 1.3.7
express: 3.0.0
My package.json file for openshift is as following.(I don't have much information about preparing json file so I use default one)
{
"name": "OpenShift-Sample-App",
"version": "1.0.0",
"description": "OpenShift Sample Application",
"keywords": [
"OpenShift",
"Node.js",
"application",
"openshift"
],
"author": {
"name": "OpenShift",
"email": "ramr#example.org",
"url": "http://www.openshift.com/"
},
"homepage": "http://www.openshift.com/",
"repository": {
"type": "git",
"url": "https://github.com/openshift/origin-server"
},
"engines": {
"node": ">= 0.6.0",
"npm": ">= 1.0.0"
},
"dependencies": {
"express": "~3.4.4"
},
"devDependencies": {},
"bundleDependencies": [],
"private": true,
"main": "server.js"
}
Thus my actual question is;
Does openshift normally runs these functions that slow or is it happening because of my mistakes?
Edit: The delay time is decreased from 2 minutes to 14 seconds. Eventhough I didn't change or repush anything.
Edit2: The delay time for connection is decreased from 14 seconds to 9 seconds by itself. And the delay time for disconnection still takes 2 minutes. My players have to wait 2 minutes to find out a player is left my game.
