Xeon performance in Paris: what really makes a game server fast

When people talk about game server performance, core counts and clock speeds only tell part of the story. The latency your players actually feel depends on an entire chain — from the silicon to the edge router — and that chain is where we focus every effort at oneSubnet.

Why the CPU matters so much

A Minecraft, FiveM or Rust server runs largely on a single main thread. That means a high single-core clock will often beat a 32-core processor with modest clocks. Our nodes run on Intel Xeon Silver 4214 CPUs, whose sustained base clock and thermal management are designed for continuous server workloads, not for short marketing peaks.

A game’s load profile is also very different from a web workload: it simulates a world in real time, tick by tick. Each tick (20 times per second on Minecraft, for example) must finish its computation before the next one, or players see visible lag. A predictable CPU that does not throttle the moment it gets hot is therefore more valuable than a boost figure on a spec sheet.

ECC RAM: the invisible insurance

All our memory is DDR4 ECC (Error Correcting Code). ECC silently corrects the single-bit errors that occur naturally from wear, heat or cosmic rays. On a personal machine, such an error means an occasional crash. On a server that runs 24/7 for months, the same error can silently corrupt a world chunk or a database.

ECC does not improve measured speed, but it protects the integrity of your data over time. It is one of those invisible choices that separates consumer hosting from professional infrastructure.

NVMe storage is not a detail

Many budget hosts still cut corners on disk. That is a costly mistake for games: saving, chunk loading, database reads for FiveM plugins or Rust mods are all bound by I/O. A modern NVMe drive delivers hundreds of thousands of operations per second, versus a few hundred for a mechanical disk.

The concrete result: a server that boots faster, backups that do not freeze the game, and database queries (the notorious “query lag” on large servers) that stay under a millisecond.

Connectivity: the critical last mile

A powerful server behind poor connectivity will deliver a poor experience. Our infrastructure is hosted in Paris, in the Digital Realty datacenter, with shared and redundant 10 Gbps connectivity across multiple transit providers. For a French player that usually means under 15 ms of latency, and for a European player under 40 ms.

Transit redundancy matters: if one provider has an incident, traffic is picked up along another path, and your players see nothing more than a brief fluctuation.

A Paris datacenter, a deliberate choice

Hosting in France is not just about sovereignty. It is also about latency for your core audience and the legal framework (GDPR) for your data. Digital Realty in Paris offers a high Tier of reliability, with redundant power and cooling, which underpins the 99.9% uptime we guarantee.

How to judge performance for yourself

Do not trust numbers alone. Before committing, ask for the exact CPU model, the presence of ECC, the storage type (NVMe or not) and, above all, the real measured connectivity toward your audience. A good host answers precisely and transparently — and that is the standard we hold ourselves to.

Game-server performance is built at every link in the chain. No single component makes the difference on its own; their balance is what decides the final experience your players get.
