OfflineImap caches the state of the synchronisation to e.g. be able to determine
if a mail has been added or deleted on either side.

The historical status cache is a plain text file that writes out the complete
file for each single new message (or even changed flag) to a temporary file. If
you have plenty of files in a folder, this is a few hundred kilo to megabytes
for each mail and is bound to make things slow. The latest status cache
is sqlite. This saves plenty of disk activity. The sqlite engine and the Python
sqlite module must be installed. The historical plain status cache is not
supported anymore.

If you switch the backend from plain to sqlite, you may want to delete the old
cache directory in '<metadata>/Account-<account>/LocalStatus' manually (the
sqlite cache stands in the 'LocalStatus-sqlite' folder).
The historical plain status cache is not supported anymore but migrating from a
very old installation using the plain text cache is still supported. In this
case, you may want to delete the old cache directory in
'<metadata>/Account-<account>/LocalStatus' manually (the sqlite cache stands in
the 'LocalStatus-sqlite' folder). First, make sure you have run the new version
of offlineimap for all your accounts so that the status cache was migrated.
