Yes, slow, both the RR Site and the New Posts Option took about 20 sec's each to come up (normally for me about 1.5 sec's), and I have a reasonably fast setup.
I was unable to log into the Forums around 11:30 a.m. EST today. After entering my user name and password I would get the "thank you for logging in" message, but the page would revert to the Forum Login page and with user name blank.
From 3:37 p.m. to 3:43 p.m. EST the forum pages and posts have been slow to load. Wiki also slow to load. Database loads in normal time.
As of 3:50 p.m. EST, performance is back to normal for me. Pages/posts load promptly.
