Recently i started a Fabric minecraft SMP for like around 10-15 players, not all the players are online tho. I made the serv on my old laptop and the srv specs are 12 gb ram, intel 15 9300H cpu. I am noticing lag in the server with just 5-6 player, is there any way i could optimize it, i alr have the necessery mods like lithium, chunky etc.
