I need help with server!!

[Forge91]

Hello, I hope someone can help me with this. Im trying to create my own server, but how ever I dot it it Laggs like ****. I've tried everything, and I have no idea what could it be. From our other computer (that is connected in same modem) I can create server that doesnt lagg, but I cant use that computer much. I hope someone can help me and tell what causes lagging in this computer. Thx

Well is it ping lag, choke lag, tickrate lag, loss, FPS, what is it?

have you set up the appropriate rates? what upload rate do you get? and how many slots did you try and put on your server. to many will cause lag.

Are you hosting the server on the same computer as you are playing from?
