Me and some players are playing into a server with too many mods, and ram comsumes are in 3-4gb of ram. But sometimes, it increases to 6.5-7.0 randomly and then the server restarts.
Actually im using 8gb ram, and the consume is around 4-5gb. Are you sure that if i take 16gb of server ram, it’s going to be ok? The map isn’t loading so good, and if we are like 4 players, it crashes.
Run a profiler using the Spark mod to see what mods you need to remove. Sounds like some mods are taking up too much CPU time (MC is mostly singlethreaded)
