compare dedicated server providers on our comparison table<\/a> and look at the network specifications \u2014 not just the monthly transfer cap, but the port speed, DDoS protection, and peering quality.<\/p>\n\n\n\nHow Game Servers Use Bandwidth<\/h2>\n\n\n\n Game server bandwidth usage is different from web hosting or streaming. Each connected player sends and receives a small, constant stream of packets containing position updates, actions, and state changes. The per-player bandwidth is low \u2014 typically 10\u201350 Kbps per player for most games \u2014 but the packet rate is high, and the server must handle all players simultaneously.<\/p>\n\n\n\n
The key formula: total bandwidth = per-player bandwidth \u00d7 number of players \u00d7 2 (for upload and download, though game servers are primarily upload-heavy). For a 20-player Minecraft server with 20 Kbps per player, the server needs 400 Kbps of upload bandwidth. For a 50-player Rust server with 50 Kbps per player, the server needs 2.5 Mbps. These numbers are tiny compared to the 1 Gbps uplink that most dedicated servers provide.<\/p>\n\n\n\n
The real bandwidth constraints come from three sources: monthly transfer caps, per-connection limits, and DDoS attacks.<\/p>\n\n\n\n
Per-Game Bandwidth Requirements<\/h2>\n\n\n\n Here are measured bandwidth figures for popular game servers based on real-world testing. The per-player numbers assume vanilla settings with default tick rates and view distances.<\/p>\n\n\n\nGame<\/th> Per-Player Upload<\/th> Per-Player Download<\/th> 20 Players (Total)<\/th> 50 Players (Total)<\/th> Monthly Transfer (20 players, 24\/7)<\/th><\/tr><\/thead> \nMinecraft (Java)<\/td> 15\u201325 Kbps<\/td> 10\u201320 Kbps<\/td> 0.5 Mbps<\/td> 1.25 Mbps<\/td> ~150 GB<\/td><\/tr>\n Valheim<\/td> 20\u201340 Kbps<\/td> 15\u201330 Kbps<\/td> 0.8 Mbps<\/td> 2.0 Mbps<\/td> ~250 GB<\/td><\/tr>\n Palworld<\/td> 30\u201360 Kbps<\/td> 20\u201350 Kbps<\/td> 1.2 Mbps<\/td> 3.0 Mbps<\/td> ~380 GB<\/td><\/tr>\n Rust<\/td> 40\u201380 Kbps<\/td> 30\u201360 Kbps<\/td> 1.6 Mbps<\/td> 4.0 Mbps<\/td> ~500 GB<\/td><\/tr>\n ARK Survival Ascended<\/td> 50\u2013100 Kbps<\/td> 40\u201380 Kbps<\/td> 2.0 Mbps<\/td> 5.0 Mbps<\/td> ~630 GB<\/td><\/tr>\n Counter-Strike 2<\/td> 30\u201360 Kbps<\/td> 20\u201340 Kbps<\/td> 1.2 Mbps<\/td> 3.0 Mbps<\/td> ~380 GB<\/td><\/tr>\n 7 Days to Die<\/td> 25\u201350 Kbps<\/td> 20\u201340 Kbps<\/td> 1.0 Mbps<\/td> 2.5 Mbps<\/td> ~310 GB<\/td><\/tr>\n Project Zomboid<\/td> 15\u201330 Kbps<\/td> 10\u201320 Kbps<\/td> 0.6 Mbps<\/td> 1.5 Mbps<\/td> ~190 GB<\/td><\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\nThese numbers assume the server is running at full capacity 24\/7. In reality, game servers are not full 24 hours a day \u2014 peak hours might be 4\u20136 hours, with smaller crowds during off-peak times. The monthly transfer numbers above are worst-case estimates. Real-world usage is typically 30\u201350% of these figures.<\/p>\n\n\n\n
Monthly Transfer Caps: What They Actually Mean<\/h2>\n\n\n\n Most dedicated server providers advertise a monthly transfer cap, typically 10\u201330 TB for a standard server. For a single game server, even 10 TB is far more than you will ever need \u2014 a 50-player Rust server running 24\/7 uses at most 1.5 TB per month. The transfer cap only becomes a concern in two scenarios:<\/p>\n\n\n\n
\nMulti-instance hosting:<\/strong> Running 8 game servers with 20 players each could use 2\u20134 TB per month, which is still well within the 10 TB cap.<\/li>\nMod download servers:<\/strong> If your server hosts custom mods or maps that players download from the server directly (rather than the Steam Workshop), the initial download traffic can spike. A 100 MB mod downloaded by 50 players is 5 GB in one shot. This is rare but can add up.<\/li>\n<\/ol>\n\n\n\nThe transfer cap is rarely the binding constraint for game server hosting. The binding constraint is almost always the port speed and per-connection limits.<\/p>\n\n\n\n
Port Speed: 1 Gbps vs 10 Gbps<\/h2>\n\n\n\n Most dedicated servers come with a 1 Gbps uplink as standard. 10 Gbps uplinks are available from most providers for an additional monthly fee. For a single game server, 1 Gbps is more than enough \u2014 even ARK with 50 players uses only 5 Mbps. You would need 200+ players on a single game server before the 1 Gbps uplink became a bottleneck.<\/p>\n\n\n\n
However, the port speed becomes relevant during DDoS attacks. A 1 Gbps uplink can be saturated by a moderate DDoS attack, making the server unreachable. A 10 Gbps uplink can absorb a larger attack before saturating, giving the provider’s DDoS mitigation system time to filter the malicious traffic. If you run a public game server that is a target for attacks, the 10 Gbps uplink is worth the extra cost.<\/p>\n\n\n\n
The Hidden Factor: Peering and Latency<\/h2>\n\n\n\n A 1 Gbps connection is useless if the provider’s network has poor peering to your players. The bandwidth between two points on the internet is limited by the slowest link in the path, and that slowest link is often the peering between the provider’s upstream provider and the player’s ISP.<\/p>\n\n\n\n
Key networking metrics to check when choosing a provider:<\/p>\n\n\n\n
\nLatency (ping):<\/strong> Under 50 ms for the majority of your players is ideal. Over 100 ms, players will notice input lag. Over 150 ms, the game is barely playable.<\/li>\nJitter (latency variance):<\/strong> Under 10 ms is good. Over 20 ms, players will experience rubber-banding and stuttering even with adequate bandwidth.<\/li>\nPacket loss:<\/strong> Under 0.1% is acceptable. Over 0.5%, the game will feel laggy even if the ping is low. Over 1%, the server is unplayable.<\/li>\nBGP routing:<\/strong> Providers with their own ASN and direct peering with major ISPs (Tier 1 or Tier 2 networks) will have better routing than providers that resell bandwidth from a single upstream.<\/li>\n<\/ul>\n\n\n\nMost providers offer a looking glass<\/strong> or test IP<\/strong> that you can ping and traceroute from your location before renting. Always test the latency before committing. A provider with a server in Dallas will give different latency to a player in London than a provider with a server in Amsterdam, regardless of the bandwidth specification.<\/p>\n\n\n\nDDoS Protection: Non-Negotiable for Public Servers<\/h2>\n\n\n\n If your game server is publicly listed in the server browser, it will be attacked. It is not a matter of if, but when. The most common attack types against game servers are UDP amplification attacks (which target the game’s query port) and volumetric floods (which saturate the uplink).<\/p>\n\n\n\n
What to look for in DDoS protection:<\/p>\n\n\n\n
\nAlways-on mitigation:<\/strong> The provider filters traffic at the network edge, before it reaches your server. This is better than on-demand mitigation that only activates after the attack is detected.<\/li>\nPer-IP null-routing:<\/strong> If one IP is attacked, the provider can null-route that specific IP without affecting your other IPs.<\/li>\nCapacity:<\/strong> At least 1 Tbps of total mitigation capacity. A provider that has only 100 Gbps of capacity can be knocked offline by a large botnet.<\/li>\nGame-specific rules:<\/strong> Some providers have custom mitigation rules for game protocols (Steam, RakNet, etc.) that can distinguish legitimate game traffic from attack traffic more accurately than generic DDoS filters.<\/li>\n<\/ul>\n\n\n\nMulti-Instance Bandwidth Planning<\/h2>\n\n\n\n If you run multiple game servers on one machine, sum the bandwidth requirements of all instances. A machine with 8 game servers at 20 players each might use 5\u201310 Mbps total, which is trivial for a 1 Gbps uplink. But the monthly transfer cap adds up: 8 servers \u00d7 200 GB per month = 1.6 TB, which is still within the standard 10 TB cap.<\/p>\n\n\n\n
The real concern for multi-instance hosting is not bandwidth but port allocation. Each game server needs its own port range, and the total number of available ports is limited by the OS and firewall rules. Plan your port allocation in advance and use a consistent scheme (e.g., base port 27000 + instance number \u00d7 10).<\/p>\n\n\n\n
Bandwidth Monitoring Tools<\/h2>\n\n\n\n Once your server is running, monitor bandwidth usage to ensure you are not approaching the transfer cap or hitting per-connection limits:<\/p>\n\n\n\n
\nvnstat:<\/strong> Lightweight traffic monitor that tracks daily and monthly usage. Install with apt install vnstat<\/code> and check with vnstat -m<\/code> for monthly totals.<\/li>\nnload:<\/strong> Real-time bandwidth monitor for each interface. Shows current upload and download speeds.<\/li>\niftop:<\/strong> Shows per-connection bandwidth usage. Useful for identifying which players are using the most bandwidth.<\/li>\nProvider dashboard:<\/strong> Most providers offer a bandwidth usage graph in their control panel. Check this monthly to ensure you are within the transfer cap.<\/li>\n<\/ul>\n\n\n\n
