Hello, please advise how you can optimize the server and configure the equipment correctly? 400-500 people play on our servers in the first 2 days after the wipe, and the server starts to hang (animations from players and other lags characteristic of poor optimization) when online reaches >400

Configuration: Core i9 13900K, 128 GB DDR 4 RAM, 2x500 GB NVMe SSD
Operating System: Windows

Tell me what important things can be done to optimize the equipment as much as possible.

For example.:

- should energy-efficient cores be disabled?

- how many productive cores does the server need for 500-600 players?

- how many servers can support such an obordoanie?

- how to minimize failures?

- how do people optimize their work for 1000 players?

Please tell us everything you know about optimization, thank you
