Hi,

I recently moved to nginx and instantly started noticing a constant hold up of 200ms to 4s on all my requests. First I thought it was my PHP scripts (mainly wordpress) taking time but then I noticed the similar delay on images and static html pages.

I created a controlled test to understand the problem:
http://adeelejaz.com/test/test.html
http://adeelejaz.com/test/test.php

Both these pages get a delay of about 120ms to 150ms (which made me rule out fpm as an issue). I checked Firebug and Chrome and found out the delay is on "Waiting" which I assume is the time it takes the server to fetch the resource.

I was using a unix socket so I switched to IP (127.0.0.1:9000) just to check if that might be the cause but I got same results.
I also borrowed my mate's nginx.conf file just in case I was doing something wrong but I cannot see anything odd. I've tried searching but most of people issues are with fpm only but in my case, my static resources also take time.

The server is a Rackspace Cloud server with a quad core and 512mb ram.

My conf file:

user www-data;
worker_processes 4;
pid /var/run/nginx.pid;

events {
worker_connections 768;
}

http {
