What is this plugin?
This plugin untracks the entities around a player that are too far away, removing their AI. And when the player gets near the entities become active again. The spigot link is for an older version but I also posted a updated version that is the same thing but with the latest version support and a few more changes. Why do I want this plugin?
Owning a SMP server that has some good days where a lot of people are online is pushing the server limits, spawning a lot of mobs and the tps is dropping down a lot, even to like 8-9 after 23-25 players which is not all that ideal. Timings show the main problem are entities, and there are not a lot of stuff I can do. A stacking plugin can help a bit, maybe raise the tps with 1 or 2 but players are really unhappy and it really does change the gameplay a bit. Also my server has a lot of spawner farms which is also not really a great touch to the performance. But this plugin seems to maybe solve this issue, and won't affect the gameplay too much.
