Coming from rainloop (not maintained any more?) I gave nextcloud mail a chance again.

(Translated ruffly: This tab makes your browser slow, stop it?)
It can happen at any time, on switchting to the tab, on changing folders, on selecting mails, on deleting mails. The server seems bored load wise, it happens even in local LAN.
I have nextcloud 25.0.1 and Mail 2.1.2 running on:
What is the best way to diagnose performance issues with this app?
It also notifies me about >6000 new emails all the time that are not new, that might be part of the issue.
