$ sudo du -h /var/lib/mysql
972K	/var/lib/mysql/mysql
156K	/var/lib/mysql/phpmyadmin
1.6M	/var/lib/mysql/koha3db
39M	/var/lib/mysql

As shown by attached screenshot there's plenty of RAM available.

I can agree that I'm low on RAM generally here, but I don't think it
should have such dramatic effects. +30 seconds is hardly usable.

I'll try to upgrade my SO-DIMMS to 2*2 GB...

No koha-error.log file found anywhere... Disabling apparmor speed it
up by 5-10 seconds.
