I just upgraded to 3.1 and my admin pages are extremely slow to render. All blog site seems to be working fine. I am running in a linux environment. There is a 120 second (almost to the second) delay from when I click on a link within admin until the time it renders. Seems like a timeout. I am in a pretty strict environment with firewalls, so if new outbound connections/ports are required in 3.1, then that could be an issue. Any thoughts or ideas what changes in 3.1 may be related to this behavior?
