How to Optimize Chunk Loading

Chunk loading optimization is about controlling how much world data the server must create, read, tick, save, and send to players.

#Build a Chunk Plan

| Decision | Good default | | --- | --- | | World border | Set before public exploration | | Pregeneration | Run before launch or off-peak | | View distance | Start moderate, then profile | | Simulation distance | Keep active ticking smaller than visual range when needed | | Resource worlds | Reset or border them intentionally |

Use the server.properties generator to create a baseline for view distance and simulation distance, then refine from profiles.

#Pregenerate With a Border

Pregeneration is most useful when it matches the area players will actually use. Pregenerating millions of chunks that nobody visits wastes storage and time.

Better approach:

1. Choose a realistic first-season border.
2. Pregenerate the overworld.
3. Pregenerate nether and end if players will explore heavily.
4. Run backups after pregeneration finishes.
5. Expand the border later if the community grows.

#Reduce Teleport Spikes

Teleport-heavy servers can load many chunks quickly. Review homes, warps, random teleport plugins, portals, and minigame arenas.

Practical rules:

1. Delay or queue random teleports during peak hours.
2. Keep public warps in pregenerated areas.
3. Avoid sending many players to new terrain at once.
4. Audit plugins that load chunks for previews or safety checks.

#Check Storage and Backups

If chunk loading freezes while CPU is not maxed, storage may be the bottleneck. Look at backup timing, disk latency, world size, and whether your host uses slow shared storage.
