Hi,

Here is odoo worker and memory calculations based on various theories and practicals:

1 worker can handle around 6 concurrent users and 6 concurrent users is 6 clicks happening at the same time. 
So, for example, if we have 60 concurrent users daily, we should use around 10 workers.

limit-memory-soft = 2000 MB X 10 worker = 20000 MB (This should not exceed more than actual RAM) * 1024 * 1024 = 20971520000

limit-memory-hard = 2500 MB X 10 worker = 25000 MB (This should not exceed more than actual RAM) * 1024 * 1024 = 26214400000

2000 MB and 2500 MB are standard values for odoo V13, odoo V14 and odoo V15.

Hi 

we need to get the information regarding the number of concurrent users then only we can determine the no of workers
