Yeah, you're not alone. Since the server upgrade it's typically taking 10 to 30 seconds to open anything whereas before things opened just about instantly. I'm sure Chris is aware of this issue and is working on it.
I noticed that Billy Mac's thread opens really slow. I think it's because his pictures are damn near full sized. Takes a while to load up. This is the only thread I have trouble with. Everything is wham bam thank you maam.
