In my case those steps helped:
zammad config:set WEB\_CONCURRENCY=4
systemctl restart zammad

Please read aboe mentioned documentation _before_ blindly adjusting settings.

Hi guys,
we also faced performance issues the last days. Fix is in stable since this morning. If you did not have performance issues before 5.2 and got some on 5.2 update then you should update when the package is ready.
