From KDE UserBase Wiki

The initial import might be slow and could use a lot of memory, especially in case you have folders with a large amount of mail. In that case per-folder check is preferred. In case the check (complete or for one folder) is finished and the memory usage is still high, you could restart the Akonadi server - as seen above - or just the maildir agent, if you use akonadiconsole. Don't worry, this high memory usage is only for initial import.
