Ok I think I fixed nginx

Yes that does seem to be a good deal better for you!

One last major thing that I strongly suggest you do, if you haven't already, is make a optimization request here:
https://www.vbulletin.com/forum/foru...-Configuration

While I kindof know my way around apache, the guy who answers threads there is a guru at what he does! It should definitely hellp you with memory settings and all of the other necessary hardware/mysql settings stuff.

Also, check and see if there are login issues after applying the htaccess. In my guide I noticed there were for me and I posted my fix on post 3 of the guide.

I can log in fine. I submitted a request. Thank for all your help. Let me know if there is anything else you can think of.

hmm yslow does agree with my expiree headers

The final thing I can suggest to you now is to try to losslessly compress your images and use css sprites. Sometimes the lossless compression can make a huge difference.



This covers the following PageSpeed Rules:

Optimize Images

If you have access to Visual Studio 2010 (grab the trial edition here which should be compatible with the addon), you can complete this step in just a few clicks using this addon

You can also use pnggauntlet which will compress images as well.

This is great to use on new skins/themes and also non animated gifs for Smileys, Signatures, Photo Album & Group Images and Avatars that your forum stores on your server!

Please note that both of these methods produce lossless images, meaning that even though it uses various methods to decrease file size there is absolutely no visual loss in quality of the image.

For non-windows users, I suggest Imageoptim & Trimage



Step 4: Add CSS Sprites.
Not compatible with VB3

This covers the following PageSpeed Rules:

Combine images using CSS sprites

2 more things from the top of my head to consider (which I haven't had a chance to try yet) are mod_spdy & mod_pagespeed from google.

Looking at it, this is one of those instances where you may just have to throw hardware at the issue. A second CPU, more ram or faster drives could help you out depending on where your bottleneck is. (From the limited info you've given us, I suspect harddrives will give the biggest win)

Before doing that, I would highly recomend looking at mariaDB as an alternative to myisam and switching fully over to nginx + php fcgi will help save some resources as well.

Well, not quite. I do agree that you may need some more hardware. Try putting the static content (js/css/html/images etc... pretty much all of your files) onto one server.

Grab a second server and use that one to only host mysql. I think your 16GB of ram should be more than enough.

Also, you may want to check out google page speed service. I've been receiving much better optimization reports recently while using it!
Page Speed 1.12 Score: 92/100 Compared to 82 or so while using cloudflare instead..

You don't need better hardware. The server needs to be tuned by a professional.
