Well.. I rarely lag on Prison except when you first log in. The Lobby is a nightmare. In the actual Prison server? I maybe see 1-2 lag spikes out of my whole time of playing for 4-5 at a time. I would ask if you running at least 5mbps down? I run 60mbps, and I have a gaming PC. I haven't had these lag spikes you guys refer to. Make sure to drop your chunks down to a lower amount as well. I used to have these "spikes" when I had my chunk load 40+. I play around 10-20 now, and the transition of everything in the server is sooo much smoother.
