Unhappy with Akonadi

[Dāvis Mosāns]

Hi,

I just want to share that my experience has been pretty much the same
so I truly understand your frustration. Unfortunately the only
solution is investing a lot of time in performance optimizations for
KMail/Akonadi. Most likely it's many different issues that show up
only under some circumstances so it might not be easily
visible/obvious where the problem is. And it's been like this for many
many years.

Best regards,
Dāvis
