The maximum server size in Factorio isn’t fixed by the game but depends on hardware, network stability, and in-game settings. While the game supports thousands of entities, player count is limited by CPU power, RAM, and internet bandwidth. Mods, map complexity, and automation scale also impact performance. Optimal setups balance these factors for smooth multiplayer experiences.
What Is Dedicated Hosting and How Does It Work?
How Does Hardware Influence Factorio Server Capacity?
Factorio’s server performance relies heavily on single-core CPU speed, as the game’s simulation runs on one thread. A modern CPU (e.g., Intel i9 or AMD Ryzen 9) with high clock speeds, 16GB+ RAM, and SSD storage ensures smoother gameplay for larger servers. Network latency below 50ms is critical for real-time synchronization between players.
Recent benchmarks reveal that AMD’s Ryzen 7950X3D processor with 3D V-Cache technology delivers 15% better UPS (updates per second) compared to standard models when running megabases. Server operators often pair these CPUs with low-latency DDR5 RAM modules clocked at 6000MHz or higher. For storage, NVMe SSDs with direct storage APIs can reduce save/load times by 40% in factories exceeding 1 million entities. Thermal design becomes crucial at this level – liquid cooling systems are recommended to maintain consistent boost clocks during extended play sessions.
| Component | Minimum | Recommended |
|---|---|---|
| CPU Clock Speed | 3.8GHz | 5.0GHz+ |
| RAM Capacity | 8GB | 32GB |
| Network Latency | 100ms | <50ms |
Can Mods Affect Maximum Server Size in Factorio?
Yes. Mods like Bob’s Mods or Space Exploration add complex mechanics, increasing RAM usage and CPU load. A modded server with 10 players might require the same resources as a 50-player vanilla server. Always test mod compatibility and performance in small groups before scaling up.
The AngelBobs modpack demonstrates this impact clearly – its advanced production chains can triple the number of active entities compared to vanilla gameplay. Some content-heavy mods like Pyanodon’s Alternative Energy require 8GB of additional RAM just for basic operations. Server administrators should use profiling tools like the built-in debug menu (F4) to monitor entity update times. For heavily modded servers, implementing chunk-based load distribution through mods like ClusterIO can help spread computational tasks across multiple machines. Additionally, disabling non-essential graphical effects in mod configurations often recovers 10-20% UPS headroom.
Expert Views
“Factorio’s server limits are a dance between silicon and software,” says a veteran server host. “We’ve pushed to 100 players on vanilla by overclocking CPUs to 6GHz and using RAM disk for saves. But modded scenarios? That’s where art meets science – sometimes removing one belt type from a mod doubles your player capacity.”
Conclusion
While Factorio imposes no hard server cap, practical limits emerge from hardware, game design, and network realities. Through strategic optimization and hardware investment, communities can push player counts into the dozens – but always at the mercy of the ever-hungry factory’s demand for UPS.
FAQs
- Does Factorio Support Cloud Server Scaling?
- Yes, using AWS or Google Cloud instances with high-frequency CPUs. However, costs rise exponentially beyond 20 players due to Factorio’s CPU-bound nature.
- Is There a Official Player Limit?
- No. The developers state any “max players” setting is arbitrary and hardware-dependent. Some public servers have hosted 100+ players during events.
- How Does Multi-threading Affect Performance?
- Currently minimal – most game logic runs single-threaded. Mods like Clusterio simulate separate factories across threads, effectively multiplying server capacity through distributed systems.
