I switched some years back to nnimap on a sql-backed imap daemon for
that very reason.

I don't know whether it still does, but it used to scan through the
groups three times every time I started.

Which took *horribly* long back on that laptop's ide drive and shared
ram/io bus.

On top of that bug, part of the issue is using the filesystem as a
database.  Anything using that style of storage suffers a superlinear
delay as the size grows.

I'd start by watching emacs with something like strace -e open to see
whether it still loops through all of the groups multiple times.

That bug still requires a fix if so.

Otherwise a general profile of a startup probably would help.
