Ubuntu websites are all painfully slow compared to basically everyone else's. Brainstorm is about the least painful, but it too loads far slower than is sensible. The worst is the forums; try comparing Fedora's forums. I can load Ubuntu forums, close the tab, and load the same page again and if it bothers to finish loading at all, it will come up slower than the first time loading any fedora forum page (cacheless.) I'm on a modem and more than once a bug report page has failed to load, and I've just blown off the bug report because after the third retry I decided it wasn't worth it to bother to keep hitting F5 and waiting for over a minute for the page to try to load and time out to try AGAIN to file the bug.
I've lost track of the number of times I've just given up on something because I couldn't load a forum thread or a bug report (just to VIEW one, let alone file one.) Granted, I have a poor modem connection, but I do NOT have these kinds of problems other places (e.g. GNOME bugzilla, Mozilla Bugzilla, Fedora forum, Drupal forum, etc.) There's no reason it should be so staggeringly much worse on Ubuntu's websites.
