I can help you configure optimal performance for your DB server, but I need to know details of your new server as well as what other services are running on the node. Shoot me a PM in IRC, or trinitycore PM (top right).
You can't just share the mysql.conf. MySQL is configured for exactly that server based on the services running and especially hardware. I also use tools to help balance the correct amount of database usage (not too little, and not too much)
I don't run JUST a worldserver on the node. It's a separate DB server dedicated for this very purpose as a DB server.
Anyhow, you don't want to configure your machine with someone else's conf, that may have more/less memory, storage, etc.. you could do more harm than good, even if it's not noticeable at that very moment.
