i understand the problem, you only have one profile field but i have 3:
that is the problem, it is not defined to the first one only. it can happen to many more users here who have more than one field.
small problem- after installing it appears 3 times in the profile, can you fix it? after some edit- i found that the problem is with: id='elProfileInfoColumn' - when i deleted it from front=>profile=>profile than i don't see anything.
it runs fast to me too.. it is maybe something with your forum or your server.. if i were you i would try to install or upgrade to 3.0 in another server and see if it is still very slow.
