Indeed. That's something which is a real pain.
However, I have seen atleast one positive improvement during the last week where a discussion thread is being rendered faster compared to what used to be earlier, after Libor identified and fixed this issue https://jira.jboss.org/browse/ORG-272
Well that ticket shows as closed, but the site speed doesn't seem to be improving.
BTW, trying to access this site with a mobile device is almost IMPOSSIBLE!
