How much RAM needed for the new Document server?

Hello everyone!

Can somebody tell me how much RAM is needed for Nextcloud with the Onlyoffice document server app - Community Document Server? Or where to find the documentation, it’s not on the app-linked Github readme page for the document server.

Thanks.

2GB for Onlyoffice document server. How is that possible? When I tried standalone Onlyoffice Document Server, it wouldn’t even start with less than 8GB… Was I doing something wrong?

Here it says 6GB… What’s the difference?
