I'm going to mention the importance of page load times since almost SEO topic boils down to traditional methods, "Content is king", and so forth.
What happens if a site is slow or not fast enough for Google's liking? The rankings will likely drop.
Page Speed is one aspect which can surpass the importance of the actual content, if it's bad enough and it can sometimes be the difference between someone using your site or a competitor.
One aspect includes the browser waiting to download the CSS / JS after having phpBB / MyBB / Wordpress / whatever backend serving the main content. While you can do some tricks like async, this doesn't eliminate the fundamental issue that the browser has to wait for that content to arrive otherwise, the page may look very broken without it's CSS.
One trick to deal with this includes serving the head block of the HTML in advance before the script has finished processing / rendering the main content as the script will often have an idea of what it wants the head block to look like long in advance and so, the browser will start loading the CSS / JS sooner.
