Tested Classic, then tested Charcoal. In the messageboards this works fine for me: I see no dropdown menus, and page loads are 6-8 seconds over several tests.
(An aside: In Charcoal the ENWorld logo does not link to the ENWorld.org main site, like it does in Classic.)
However, as Morrus observed in another thread, I too am still getting dropdown menus on the main site. This seems to slow these page loads down significantly. Main page: about 25 seconds. (Refresh tests 25, 25, 27 sec.) Preferences: about 30 seconds (Refresh tests 32, 31, 32 sec.)
For the moment I'm personally skipping the main page and jumping directly into the messageboards when I visit.
