As an update:

We began testing our data upgrading to MGOS 2.0 RC4 without using the fusion library, and we are noticing the same issues. The AGG renderer actually causes mgserver.exe to lock up at small zoom scales; today it happened at 1:254, whereas the GD renderer has yet to lock up, but it still takes a good period of time to update the map extents. Compared to MGOS 1.2 with the same dataset, both renderers perform worse when zoomed to a small scale, where, otherwise, they take only split seconds to update when zoomed far out.

Has anyone seen this behavior with their data, as this could be a necessary function for our clients?

I have experienced extremely long refresh rates when the zoom scale is really
low (~1:33 or so). The time it takes to refresh for the Sheboygan example is
at least 10x normal, and on a custom map, MapGuide server pretty much hangs
at ~1:236 (currently sitting and waiting). Has anyone else noticed this
behavior at low scales?
