Things have improved in 2.28 (I'm  now using 2.28.2 in testing), but are
still slow.

I've seen the performance is highly dependent of the size of the INBOX.
When I delete the INBOX and start fresh, it works quick. When it starts
to grow, it gets slower and slower, when starting up and when switching
virtual folders.

It is also dependent on the number of vfolders: the more vfolders, the
slower. In particular, if vfolders are dependent of small inboxes,
performance is reasonable. But as more vfolders are defined and/or they
are dependent on larger mboxes, performance slows down.

I guess it all has something to do with the implementation of mbox
indexes or something...

Before the migration to sqlite, performance was much better...

[No, I'm sorry, but I see no noticeable improvement with Olivier's
patch.]
