You can try turning on the debugging features on W3TC and then look at the comment at the end of the HTML to see if it can tell you what is taking so long. If it isn’t pointing to anything you should escalate with support and if you still don’t get a response consider changing hosting (but make sure you don’t change to another one that will be just as bad).

Something must have been wrong on the Godaddy servers (overloaded possibly) and they got it sorted out which brought the times back down. You can ping their support team to see if they can give you more information but it’s likely that they won’t.

Nearly two months after site have Long TTFB problem. Finally I found the problem is W3TC Plugin. After uninstall this plugin and installed WP Super Cache on my site. The problem get fix and I get the best test result!

After some research, I found W3T Cache is not suitable virtual host, at least to the VPS Caixing and W3T do not recommend using the form of a disk cache. This plugin will using a resource-intensive cpu or hard disk I / O.

You can check out my test result below:
