I have a 100Mbps internet connection. I nearly closed the page thinking it was broken as I sat looking at a blank white screen. Only 10 seconds later as i was moving the cursor to close tab button did it render. On looking the homepage is 11M of artifacts and as it's a single page app nothing is rendered until it's all downloaded. Terrible UX.
