I started a new thread specific to speed, but I'll give a bit of a summary here too:

I had a meeting today with a number of people internally about the speed of this update. There are now a lot of internal people digging throught the forum internals and hardware to see what can be tweaked or changed. There have been several since the migration, but more have been pulled on. I was told that the vBulletin's support team has been brought in as well.

We know there is an issue. (You guys have made sure I know , and I've passed that along to the point just short of being annoying internally). It seems to be a hard issue, but it is one we know we have to get fixed. The update is.... they are still working on it. When they stop saying that, then I'll get concerned.

Brad!
