When I analyze the website's page load speed in Chrome I can see the wait time (where the return response files of the sever are being generated) is 55ms and total page load time is 1 second or much less. When I run the test via www.pingdom.com/, gtmetrix.com/, or the Google speed test tool, the wait time is 1.8 seconds or more and total page load time is 3 seconds or more.

The page is fully cached and the cache has been warmed.

Any ideas on why this would happen? The efforts I have made so Google would see my site as fast loading will be lost.

Please don't comment about all other optimization tips like gzip and minifying css files. I am purely asking about the wait time and/o its effects on ttfb.

The physical distance (and infrasture) that your site data must travel plays a large part in the TTFB (time to first byte) and overall download speed of your site.

If you and your server are located on the same network, or even the same country, then the speed is going to be a lot quicker than someone (or a 3rd party testing tool) located on the other side of the planet.

This is one of the main reasons for using a CDN (content delivery network). Your content is distributed over a number of servers around the world. This results in your content being served from a server closest to the user viewing your site.
