First Time Byte - "F" - everything else scores well

RE: First Time Byte - "F" - everything else scores well
Just to make sure it is absolutely clear, none of the CSS, images, http requests, etc will do ANYTHING for your first byte F problem. Those are all front-end optimizations (and should still be done) while the first byte time is a "back-end" problem.

Outside tools can't give you visibility into what is going on (it is a black box). Tools like New Relic work great for profiling your back-end and telling you where the time is going. Otherwise you have to try some things out blindly, instrument your code by hand or see if there are any plugins that can give you the performance information.

Since you don't have root access I'm assuming you are on shared hosting. More often than not the problem is slow database performance (combined with plugins making lots of database queries), particularly on shared hosting. You can try uninstalling any plugins that are not critical to your site and I believe Joomla has some page caching capabilities that you can turn on in the site settings.
