I am currently working with a client that last time I checked was averaging 8-9 SECONDS for their TTFB (time to first byte). So as you can imagine they are looking at a 12-14 seconds page load time. I have done some research on how the WordPress architecture could affect the TTFB and I'm a little confused.
I guess my main question is could WordPress be responsible for such a high TTFB or does that smell more like a hosting/hardware issue? Or could WordPress return those types of delays if configured incorrectly?
Any information would be helpful at this point.
