      just upgraded my minecraft server to 1.21.1 and it doesn't look like it wants to adhere to the Xmx6G command given at startup. first at startup it seem fine with 6G, but as soon as a player joins the server it grabs all the memory it can from the system and it also uses 80-150% more cpu power than 1.21 does. the server becomes very unstable/laggy as the system becomes overloaded.
