Do a -p <profiledir> and send me the resulting dir. I'd be interested to
see where we spent our time in your setup (although waiting for IMAP
connections/responses usually trumps everything else).

A big part of our time is spent retrieving (&comparing) all UIDs on the
server and the corresponding flags. This can be reduced with the
-q(uick) option in cases where you have email boxes with less churn.

But, as I recall your repository deal with disjunct folders anyway:
folderfilter = lambda foldername: foldername in ['INBOX']
folderfilter = lambda foldername: foldername in ['[Gmail]/All Mail']

and therefore there is no duplicate retrieving happening there (besides
getting the folder list). So not sure if and how much we can save.

The first 2 accounts can be run in parallel, the third should probably
be run after the BoostProLocal sync finished.

Per-folder read-only would certainly be nice for many.

LocalStatus should be pretty much the same across your folders, the
plain text format is simply: 
40960:S                     =UID:messageflags 
with one entry per line. So you could synchronize and share things, I
