Every FiveM server requirements table you have read was invented by a company selling servers. Cfx.re publishes no hardware spec at all. Here is what actually determines whether your server runs well.
Search for FiveM server requirements and you will find a dozen neat tables: 4 vCPU, 8GB RAM, 100GB NVMe, "recommended for 64 players". They look authoritative. They cite nothing.
Cfx.re does not publish hardware requirements for FXServer. Not a minimum, not a recommendation, nothing. The only system requirements in the official documentation are for the client, and those are just GTA V's own specs. Every server spec table you have read was written by a company that sells servers.
That is not a conspiracy — a host has to put something on the pricing page. But it does mean the numbers you are anchoring on have no authority behind them, and you should stop treating them as if they do. Here is what actually determines whether a FiveM server runs well.
The one architectural fact that explains everything
FXServer runs a few threads. The one that matters is svMain, and here is the fact that should drive every hardware decision you make:
svMain ticks at 20Hz — a 50ms budget — and every single server-side resource ticks on it.
There is no per-resource isolation and no spreading of script load across cores. Your framework, your inventory, your jobs, your dispatch, your custom scripts — they all share one thread's budget, in sequence.
The consequences fall out immediately:
- Single-core clock speed is what matters for script performance. Cores 5 through 32 are not helping your Lua run faster.
- Not "makes it slower" — stalls it. A synchronous loop or a slow SQL query freezes every other resource for every player.
