The page is a dumpster fire:&lt;p&gt;Before Polymer (current YT framework) YT video page weighted somewhere around 50KB (10KB compressed) and was ordinary HTML + 1MB js player (400KB compressed). As soon as HTML part loaded the page was all there.&lt;p&gt;Now its 600KB (100KB compressed) JSON + additional 8MB desktop_polymer.js (1MB compressed) that needs to be compiled&amp;#x2F;interpreted before it even starts building the page client side and anything starts showing up. 1MB js player is on top of that.</text></item></parent_chain><comment><author>mrweasel</author><text>It truly is a terribly site, in terms of performance. Streaming HD content used to be the &amp;quot;hard problem&amp;quot;, but now it&amp;#x27;s displaying the site hosting the videos that the issue.&lt;p&gt;You can stream HD content on the lowest end device, or hardware almost 10 years old. The same hardware just isn&amp;#x27;t powerful enough to let you use the YouTube website in a performant way. I cannot fathom how YouTube doesn&amp;#x27;t see that as a problem.</text></comment>

That fake paint stuff is terrible too.&lt;p&gt;Here&amp;#x27;s something to try, resize youtube horizontally and watch your browser grind to a halt. At least in the case of Chrome for me.</text></comment>
