Huge disk I/O during login (Plasmashell?)

[Frank Mehnert <frank.mehnert@gmail.com>]

Hi,

for a few weeks I experience a huge disk I/O when opening the KDE5
session. Logging in from sddm takes ~2 minutes. I run Sid with the
latest updates: The usual plasmashell desktop with Kmail/Akonadi/
Baloo but file indexing is disabled. I have a local mail folder of
~2.7G and Akonadi/mysqld show some activity during session start.
Just a normal notebook hard disk (no SSD).

But I think that ''plasmashell --shut-up'' provides a significant amount
of disk I/O when opening the session and that's weird. I have almost no
activities configured, only panel + task bar, a single static background
image.

Any idea how to decrease the disk load during login?

Thanks,

Frank
