How to change chunk compression on a Minecraft server

Set region-file-compression=lz4 in server.properties and restart the server. Chunks save with faster lz4 compression but use more disk space.

region-file-compression

Sets the compression used when saving chunks to region files: deflate, lz4 or none.

region-file-compression=<algorithm>

Examples

region-file-compression=lz4

Faster saving, bigger world files.

Values

ValueWhat it does
deflateDefault Smallest files
lz4 Faster, larger files
none No compression

Arguments

algorithmRequired
The value to write after the equals sign.

What it does

deflate gives the smallest files, lz4 saves faster with larger files, and none skips compression. Only newly written chunks use the new setting.

Good to know

  • Changes take effect after a server restart.

Run it on your server

On a SLASHPLAY server, type it in the Console tab without the leading slash; in game, operators type it in chat with the slash. New to this? Start a Minecraft server first.
