Hi guys.

I have been optimising my site as best I can.
My page speeds are pretty good, but you ALWAYS seem to get some sort of extra advice!

Anyways , ran a test and results are below:
Combine static CSS and JS files: 0/100 seems to be a problem.
Any advice on what I can do here?

[b][b][b]Details:
First Byte Time (back-end processing): 0/100

1824 ms First Byte Time

If you have a link to the actual test results that would be very helpful (I find looking at waterfalls a lot more useful than checklists).

1.8 seconds for the server to respond is quite long. That is going to be a function of your app (on the server side) and your hosting.

21 separate javascript files in the top of the document is absolutely killing you (same goes for the css files but they aren’t quite as crazy). If yo can you should merge them into as few as possible and break them into two - one that needs to be loaded before the page content (preferably as small as possible) and one that can be loaded at the end of the body.
