Pagespeed (and my favorite: Gtmetrix), are very revealing. You would be surprised how many big, tech-savvy companies have abysmally performing websites.
It is also interesting to see the details of all the baggage that something like a single YouTube embed inflicts on your site performance. Sometimes it is over 50 individual server calls as well!
I honestly believe that Google has been downplaying how much this hurts your search rankings. The best first step for improving SEO (IMHO) is to make your page load fast. Usually, it is a fairly easy fix and your visitors will be rewarded as well.
