Hey the interface on YouTube loads super slowly for me. The change appeared a few months ago. I'm not talking about the video streams, but the ajax loading of the UI. Whether it's opening a new youtube tab or navigating between videos within youtube, it takes forever. Chrome/Safari -> same deal, 30 seconds delays is what I observe. My macbook pro is 10 years old, the problem doesn't appear on more recent hardware, but still youtube shouldn't be the slowest website to load on my machine. I can load spotify.com just fine in about 5 seconds.
