Compression

Packet compression reduces bandwidth usage for both Java and Bedrock clients. In pumpkin.toml, compression is configured independently for Java and Bedrock networking, as well as world chunk compression.

Network Compression

Java Edition

pumpkin.toml

[networking.java.compression]
enabled = true
threshold = 256
level = 4

Bedrock Edition

pumpkin.toml

[networking.bedrock.compression]
enabled = true
threshold = 256
level = 4

Configuration Options

• enabled: Enables network packet compression.
• threshold: Minimum packet payload size (in bytes) required before triggering compression.
• level: Compression level (0 to 9, where higher values trade CPU time for smaller packet sizes).

World Chunk Compression

Chunk compression settings control how stored world chunk data is compressed on disk.

pumpkin.toml

[world.chunk.compression]
algorithm = "LZ4"
level = 6

• algorithm: Compression algorithm used for chunk data. Supported options are "LZ4", "ZLib", "GZip", and "Custom" (default: "LZ4").
• level: Compression level for chunk data (default: 6).
