I still do not know what caused it and how it got fixed. But with Qt 
5.14.2 (instead of the former Qt 5.12 in Debian) and probably other 
updates in Debian this regression is gone.

Synchronizing mail folders is much faster again.

The other issues remain, but are not as severe now that the operation 
that is done needlessly is much quicker again.

Thanks to everyone who may have been involved in the fix. Maybe… it was 
that Akonadi 20.04 did not like Qt 5.12 or maybe it was whatever…

Best,
