I'm new to this server thing and am having issues with lag. Iv'e followed a you tube guide as to how to set up the server and all went fine however there is lag on the server. my fps is well over 150 so it's not that. I've tried running the normal minecraft server and that one runs perfect(0 lag). but the forge one is bad for some reason. Iv'e even taken all the mods i have on it off but it still runs bad. my pc is quite beefy with 12gb of ram. this is what i get when i /forge tps: Mean tick time: 3.151 ms. Mean TPS: 20.000
