Stumped on Further Optomization (TTFB)

RE: Stumped on Further Optomization (TTFB)
Are you using rocket loader or some of cloudflare's other advanced optimizations? If something is deferring the javascript on the page to load later it could explain why the ads are loading later.

At this point to improve the ttfb you will probably want to install something like New Relic that will tell you where the server is spending the 1 second of time.

From the looks of things, their VPS packages are sized based on RAM and disk space but I don't see any discussion about CPU allocation across the sizes.

Are they managing the server for you or is it up to you to manage? The reason I ask is that there are a lot of system/server level things that you can tune to make php serving a lot better and it would be worthwhile to look at:

- Using Nginx along with php-apc and php-fpm
- Tuning APC's shared memory cache
- Enabling W3TC caching (with APC or memcache)

When you upgraded the server it looks like the server was not keeping connections alive so I get the strong feeling that the server software stack isn't configured particularly well.
