Does the can’t keep up message continue to happen frequently throughout gameplay?

That message is common and somewhat expected right after the server finishes booting. You should be concerned more if it keeps doing it repeatedly during play.

The Log - Files is just a short section to show what my problem is. Well if the server is running a little bit longer the console nearly spam it with that message. Sometimes it is more than “10000ms behind”.
Edit** here are my server.properties too.

How can I pre-generated a new world ? Is there any mod / plugin to pre-generate the chunks ? and thanks for the help.

by issues with loading itemstacks on metallurgy’s side do you mean these kind of errors? @thesilentecho

Well, I can say for sure it’s not the issue, it’s the fact the game tries to load some recipes for items that have been disabled in the config
