I don't know what you did there, but it takes about 8 seconds on my desktop before it displays anything. Talk about "accelerated".
Edit: I checked with the Developer Tools, but I have no idea what is going on there. Assets are fully loaded within 500 ms, and then it just sits there for another 7.5 s before rendering anything at all. (I will note that cdn.ampproject.org is blocked by default in my uMatrix.)
