Internet Requirements for Minecraft Multiplayer – Bandwidth, Latency & Server Specs

Why It Matters

• Upload sends your position, block changes, inventory – critical for server sync.
• Latency causes rubber-banding, delayed block placement, combat desync.
• Players + Entities + Redstone increase bandwidth linearly.

Server-Specific

• Realms / Bedrock dedicated: 2–5 Mbps up per 10 players.
• Java Paper/Spigot: configurable; vanilla ~100 KB/s per player up.
• Modpacks (FTB, ATM): +50–200% bandwidth.

Quick Test

Run speed.cloudflare.com or DSLReports (bufferbloat test). If bufferbloat > 100 ms under load, enable SQM/QoS on router.
