I am using the Odoo community edition in v17. I want to run an e-learning site. There will be 10-15 internal users and 8000-10000 e-learning portal users. Around 5000-6000 will be active users. Can anyone please tell me the calculation of these values for the Odoo self-hosted server setup with multiprocessing?

1. Number of workers
2. limit_memory_hard 
3. limit_memory_soft
4. max_cron_threads   

Also what should be my server specification? How much RAM and CPU will be required?

Thanks in advance.
