My word, what is that page doing? Just opening it is enough to slow my laptop to a crawl (it isn’t the fastest in the world, but it can handle most web browsing just fine). Peeking at the Chrome DevTools shows it’s using over 500MB (not a typo!) of RAM. I checked the Chrome task manager about a minute later, and it was using 1,811,020K of memory. Why? This is a bit ridiculous.
