NetworkSettings

Server response to RequestNetworkSettings. It fixes the compression algorithm and threshold for every following batch, plus the render-distance throttle the client applies to other players.

8F 01              // header
01 00              // threshold = 1 (compress everything)
00 00              // algorithm = zlib
00                 // client throttle off
00                 // throttle threshold
00 00 00 00        // throttle scalar 0.0

Structure

Field	Type	Description
Compression Threshold	uint16 (LE)	Minimum raw batch size before compression kicks in (0 = off).
Compression Algorithm	uint16 (LE)	0 = zlib (raw deflate, level ~6), 1 = Snappy, 0xFFFF = none.
Client Throttle Enabled	bool	Whether the client throttles entity updates for other players.
Client Throttle Threshold	uint8	Player count at which throttling starts.
Client Throttle Scalar	float32 (LE)	Fraction of actors skipped per tick when throttled.

Compression Algorithm values

0 ZLib — raw DEFLATE

1 Snappy

0xFFFF None

Notes

Still sent uncompressed; the server enables compression only after this packet is flushed.
From the next packet on, every 0xFE batch carries a 1-byte algorithm marker (0x00 zlib, 0x01 snappy, 0xFF when below the threshold).
Threshold semantics: 0 disables compression, 1 compresses everything, otherwise the minimum batch size in bytes. Vanilla servers typically send 1; gophertunnel defaults to 256.
