--- Comment #6 from Martin Steigerwald  ---
Thank you Roman for your report and Thomas for your comment. Sorry for taking
long time to reply.  If you still see performance issues please open new
reports. But please follow the
following guide lines to avoid unnecessary work for the developers:

- Ideally test with KDEPIM and Akonadi 15.08. It contains some performance
improvements like the binary protocol.

- Otherwise at least use KDEPIM 4.14.10 and newest Akonadi 1.13 you can get as
it already contains some performance improvements.

- If you can wait, please retest with KDEPIM and Akonadi 15.12 once they become
available for you. Akonadi 15.12 will contain *massive* performance
improvements implemented by Dan due to new database indexes, optimized queries
and leveled file_db directory. All of these are in master already, so if you
dare use kdesrc-build to compile KF5, kdepim and kdepim-runtime. I am using
this currently and it basically moves the bottleneck to KMail (slow threading
for example). It is a *huge* improvement. Also Volker and others work on
performance improvements in KMail as well.

Thank you and greetings from KDE Randa Meetings,
Martin

The problem reappeared again. I selected a completely empty folder for the
maildir resource, kmail is much more responsive now.

Yeah, removing and readding the local maildir resource fixes the problem for
me, too. Thanks for the hint.

It seems that removing some broken maildir resources and recreating akonadi db
fixed the problem here.

There's a similar problem on Ubuntu with the latest 4.11 packages - it takes
ages to display a message or process it in any way. Kontact, akonadiserver and
mysqld processes utilize up to 100% of CPU.

Debugger in akonadiconsole is being flooded with messages similar to the one
below, looping for all the folders:
