"One how do u know the prison server will be full, maybe ccg hates prison as a collective group."
"Two if u can say that skyblock and creative and factions for the fact are running quite fine with a straight face, please pass me whatever ur smoking I want some too. All three of these servers are laggy as hell, most of them crash every hour or so. Skyblock and creative on ccg are far from working perfectly fine."
For the most part, skyblock is laggy due to the number of entities that it holds. Prisons does not allow player-spawned entities or access to an overworld that can be explored.
Factions is laggy due to a bug with the /sethome command, otherwise I find it to be fine most of the time.
Creative has corrupted chunks and is extremely old. It has a lot of lag machines all over its world.
There isn't much that can actually make prisons lag
