What this tool is for
Most servers are sized by guesswork and then either pay for hardware they never use or drop to twenty frames on a full night. This calculator estimates CPU, memory and bandwidth from player count, script count and your hardware, and tells you which of the three will run out first.
How to use it
- Step 1:
Enter your realistic peak player count, not the slot number in the server list.
- Step 2:
Enter the number of active resources. Frameworks like QBCore count as a couple of dozen on their own.
- Step 3:
Add your hardware, cores and memory, to see which limit you hit first.
- Step 4:
Read the recommendations. They are ordered by effect, the top one is worth the most.
Frequently asked questions
Why is single core performance more important than core count?
The FiveM server runs its main logic in one thread. A CPU with many slow cores loses to one with fewer fast ones. Look at single thread benchmark scores, not at the core count.
How much RAM does a FiveM server need?
The server itself is modest, but the database, the resources and the player state add up. Eight gigabytes carry a small server, a full framework server with a hundred players wants sixteen or more, mostly because of MySQL.
What does OneSync change?
OneSync moves entity ownership to the server, which is what allows more than 32 players in the first place, and it shifts load from the clients onto the server. More players means more server CPU, not just more bandwidth.
My server lags but the CPU is idle, why?
Then it is a single resource blocking the main thread, not a hardware limit. Open the resmon in the console and look for a script above one millisecond. One bad loop costs more than fifty well written resources.
