Xcode 3.0 and later are only supported running under Objective-C
garbage collection.
Please file a bug with some details showing how to reproduce the
slowdowns you see. As Jens pointed out, there are a great many large
projects that are built with Xcode.
One suspicion I have, given that you also mentioned "generation of
snapshots," is that you have some deeply-recursive header paths set up
in your projects. In this context "snapshots" may refer to how Xcode
generates its dependency graph, the performance of which can be
affected if it has to traverse a huge number of directories searching
for headers.
Another thing I strongly recommend is trying Xcode 3.1 instead of
Xcode 3.0. It's always worth trying the latest version before
reporting issues in the previous version; it's always possible that
something you're running into has already been found and fixed. You
can have multiple versions of Xcode installed side-by-side, and Xcode
is easy to uninstall and reinstall, in case you're concerned about not
being able to roll back.
