You did not have that with MariaDB or PostgreSQL? Do you see any Akonadi process activity? I think SQLite3 should be running within Akonadi's main process: /usr/bin/akonadiserver. I did have those pauses during POP3 retrieval also with MariaDB and PostgreSQL. In fact I have them since a very long time. And I think the issue is even known upstream: Look at how to improve pop3 support https://invent.kde.org/pim/pim-technical-roadmap/-/issues/36 Also I do not see any relevant KDEPIM / Akonadi process activity. It is just sitting there, idle. Or waiting on… whatever. Best, -- Martin
