Hello! I've just started getting an space engineers server by verygames and we play daily on your/our server with fun. In the beginning everything wen't fine, but now were getting big, with bigger ships and platforms, the server gets really laggy. We're online daily with +-6 people and i have an server with 8 slots. Now i know that i can upgrade my server with more slots but will this also resolve the lag that we encounter? Or is there an other solution of getting rid of this lag.
