WHY CHUNKY ON A SERVER

New-chunk generation is the single biggest lag source on survival servers — every explorer at the border makes the whole server pay. Chunky removes it up front: one command generates the world out to your border before anyone gets there.

Run it on day one, overnight. From then on exploration costs almost nothing, which is why pre-generation is standard practice on every serious public server.

Best insurance against exploration lag

From zero to playing in three steps

STEP 1

Create the server

One click creates a Paper server with Chunky staged (it also runs on Fabric/NeoForge servers).

STEP 2

Pre-generate

From the live console: `chunky radius 3000` then `chunky start`. Let it run — a few thousand blocks takes a while on any host.

STEP 3

Set a border

Match a world border to what you generated (`worldborder set 6000`) so nobody outruns the pre-gen.

Pairs well with

Questions, answered.

How long does pre-generation take?+

Roughly proportional to area: a 3000-block radius is ~1.4 million chunks and typically runs a few hours. Start it from the console and leave it — Chunky resumes if the server restarts.

How much RAM does pre-generation need?+

Generation is more CPU than RAM; 4 GB is comfortable. What matters is that pre-gen time is one-off — after it finishes you can run the world on a smaller plan.

Does Chunky work with Terralith or other worldgen mods?+

Yes — it generates whatever your worldgen produces, which makes the pairing ideal: Terralith terrain is expensive to generate and free to visit once Chunky has done it.
