    I came to submit this video as well, but the search at the bottom of the HN page did not find my link. Fortunately when I submitted, I was redirected to this page rather than creating a new link! So somehow the submission page has better search than the website search.

  Expanding on a list of techniques taken from another HN post ( https://news.ycombinator.com/item?id=41883893 https://news.ycombinator.com/item?id=41883893 ): - Server delivers HTML, not JSON - Pre-loading product page HTML on hover - Properly enabling caching on the CDN - Using service worker caching - Using ASP.net - DNS pre-fetching entries for other image and web domains - Pre-loading fonts that CSS will later load, as well as some images - Critical CSS inline: put the structural CSS for layout in <header> in a style tag inline, without fetching anything - Assign fixed pixel width and height to image to improve layout speed (this technique goes back to the 1990s!) - Javascript delivered to the page is a subset of all javascript, based on what's needed - Uses Yuyi JS library, a 2008 Yahoo library, plus jQuery - Still ~800kb of Javascript, but the focus is getting HTML on the page first These are all observations, so it's not clear if all or some are crucial for performance.
