[Warning: I know very little about gnus, perhaps just enough
to be dangerous and you probably already know all this, but just
in case... The bit that caught my attention is the slowness of
the uid search command on some versions of Courier, which seems...
related.]
Perhaps this bit from the Gnus docs might help?

Seems to have something to do with the agent? In my case, both
gnus-agent
and
gnus-agent-cache
are t, but I have no idea how to set up nnimap, so I can't check
any of this.
