So I was adjusting the Database server, changing database table engines. Then I set the innodb pool size to a too high value, and our database server went to eat up all the RAM. That caused the Linux Swap Daemon to start swapping RAM to disk (in order to extend RAM slightly). This slowed down the server to a stand still.
We got the server restarted and I reduced the setting again, to request less RAM. Perhaps in another week, we can consider increasing the RAM, so our database server can do more caching, speeding up fulltext search. But maybe at a later date.
So it's fixed now.
