I'm not sure what you're using to pull data on pages like "all updates" or "edit update", but it's unbearably slow and in some cases just never loads. It's smart to load the basics first like titles of old updates and the list of them, etc but the API for fetching the send count, percentage opened, total view count, etc is attrocious. I've tried this on multiple computers, IPs, and networks so it's definitely not client side. Maybe try caching that info once you calculate it or something.
