Try using the Board Index controls, they are both at the top and bottom of the pages. Also there is a little symbol in the lower right hand of each of the posts that will jump you to the top of the page without scrolling. Those are the controls I use, they work pretty fast.
As for the site speed, I think there are still some minor glitches with the server, hopefully we get those resolved soon. This morning, I noticed some pages were timing out. But things seem to be working alright now, for the most part these pages will load much quicker than the old format. Just gotta work some bugs out yet.
