Comment 18 for bug 909022

Don't know whetherit is the same reason as back in 2011, but there's still a major performance impact of mysqld/akonadiserver in Kubuntu 18.04 (akonadiserver 5.7.3).
mysqld takes 25% and akonadiserver 20% CPU permanently.
I did the delete (.local/share/akonadi and .config/akonadi) a few months ago (on 16.10), but a few days later the issue has been back again.
I have 12 imap ressources configured, but told them to just sync from twice a day up to 4x/day, so this can't be the reason.
Strange feeling to just browse the web (not even having kmail open) with cooler sounds like playing a HQ game... :-/
