Dear All, Investing a few hours, I did revert to Gluster 3.12.15 from the oVirt repository. With the same settings, the system does work as fast as before. That required two tries. It looks like restarting Gluster after volume deletion and downgrade was not enough. The system needed to be rebooted. The uncomfortable thing is that it is not obvious why the problem did happen and if it will happen again once an upgrade from 3.12.15 becomes more pressing.
