Well, that Akonadi is only able to do one thing at a time is not 
completely accurate. I believe it applies to the Akonadi server itself, 
but not the activities of the individual resources like POP3, IMAP and 
maildir resource. So several POP3 and IMAP resources can retrieve mails 
simultaneously while the maildispatcher agent can send a mail… however 
if there is anything to process centrally on the level of the Akonadi 
server… the Akonadi server can only do one thing at a time. So if there 
is a sync of a local maildir, then the Akonadi server itself does not 
respond to other resources until the synchronization is done.

There is a way to mitigate this a bit: The resource could synchronize 
maildirs in batches.

And there is a way to fix it: The Akonadi server can do several things at 
once and schedule between them or put it into different processes and 
threads and let the process scheduler of the operating system do the 
scheduling.

Best,
