How to change network compression on a Minecraft server

Set network-compression-threshold=256 in server.properties and restart the server. Packets over 256 bytes are compressed; -1 turns compression off.

network-compression-threshold

Sets the packet size, in bytes, above which network packets are compressed.

network-compression-threshold=<value>

Examples

network-compression-threshold=256

Default.

network-compression-threshold=-1

No compression, for proxies on the same network.

Arguments

valueRequired
The value to write after the equals sign.

What it does

Larger packets are compressed to save bandwidth at the cost of some CPU. Set it to -1 to turn compression off, which helps when the server sits behind a proxy on the same network.

Good to know

  • Changes take effect after a server restart.
