NodeJs web sitesi TTFB çok yüksek ve site çok yavaş çalışıyor

Question

Express & Jade ile bir web sitesi oluşturdunuz. Basit giriş sayfasını çok daha az içerikle yüklediğimde, o zaman bile yüklenmesi çok zaman alıyor. Bu TTFB çok yüksek (ekran görüntüsü ekli.) Aşağıda benim app.js kodum var. Neyi yanlış yaptığımı bilmiyorum.

Ben de app.js gelen tüm veritabanı ile ilgili çalışmaları kaldırıldı ama hala aynı sorunla karşı karşıya gelmiş

// Packages 
var express = require('express');

http.createServer(app).listen(1234, function() {

app.js. Herhangi bir yardım önemli olabilir. Böyle bir şey kullandık
