I have just checked my Server and it is running relativly low on RAM. There are currently no users on anyone of the Services Installed (Jitsi, Rocket.Chat, OnlyOffice Workspace) as they're all still in configuration, but I got 15.6 GB Ram Usage where a significant Part comes from Messagebus.
Is this normal? Is there a way to reduce Ram Usage?
