Raw Server Link (Skip DNS): http://173.247.246.58/

Waterfall view (Webpage Test):

I recently moved to a new server. All PHP scripts and resources stayed exactly the same. The new server is an Inmotion Elite Dedicated Server.

Average server load:

Server load 1.25 (8 CPUs)   
Memory Used 14.14% (1,137,916 of 8,048,804) 
Swap Used   0% (0 of 4,095,992)

As a network owner, having a quick and nifty site is a top priority. I can't afford to have 2-4 seconds of random waiting time for my members when navigating through-out pages. The old server never did this, it loaded fine.

Since the server load appears to be fine and the PHP scripts are the same, I want to assume it is something with some Apache settings or something like that. I really cannot tell. I tried running the two scripts listed in the Top Answer of the question posted above, but both had long wait times...

I talked to the hosting company but they didn't really know what was going on. Any help with this issue or tests that I can do would be greatly appreciated :)

Probably the most effective solution is to use a CDN with native HTML caching capabilities (static and dynamic). TTFB relies on your ability to quickly process the HTML on the origin server, you can skip processing time altogether by serving a fresh cached copy from CDN.

I wrote a post about it recently, which looks into TTFB delay factors and average load time of different resources (based on data gathered across 1B sessions). You may find it useful: http://www.incapsula.com/the-incapsula-blog/item/809-using-cdn-to-improve-seo-and-ttfb
