10 Ways to Improve Your Site Speed

What you can do about it:

8. Put style sheets at the top of the page. If your site uses cascading style sheets, make sure your CSS loads first so that your pages can start rendering right away.

9. Move blocking JavaScript to the bottom of page or use asynchronous versions of these scripts. Ideally, you want your third-party content to load at the same time as the rest of the page, but if asynchronous versions of these scripts aren't available, move the synced versions to the bottom of the page.
