Flex Build 3.1 FlexViewer Map Rotation and Zooming in On Map

I have a FlexViewer 3.1 application that I just recently applied map rotation to in the config file. Before applying the map rotation I was able to zoom in very tightly on the map (Let's say 1:600) very quickly (1-2 seconds). With the map rotation applied I can zoom tightly into the map with a decent response time when only a few (1 or 2) layers are visible. If I have all my default layers on, I am only able to zoom a small way into the map (Let's say 1:64,000) before I am unable to zoom in any more and the browser freezes.

Is this expected behavior as it takes longer to render the map when it is rotated?

Has anyone else experienced this behavior? If so, is there a way to fix this problem?
