On that URL, the opening paragraph of text loads immediately, but each additional UI element takes about 10 seconds to load. The pair of buttons below the opening text, ~10 seconds. The first table, ~10 more seconds. And so forth. The page is unresponsive most of the time - I tried to copy some text from the page to paste it here, but the browser is pegging the CPU and I can’t even copy text. The JavaScript is clearly doing something in a tight loop.

Best of luck!

Thanks for checking. I will definitely do something about it. I did some tests and understand the problems.
