CPU Sizing

1 core supports up to 200 active users, but the application can be a bit slower due to having all workers and background jobs running on the same core. 2 cores is the recommended number of cores and it supports up to 400 users

The number of core CPU can roughly be estimated by the number of users divide by 200. For example, 500 active users = 500/200 = 2.5 so need to round up to 3 CPU cores. For more accuracy, the complexity of your application and transaction should also be considered.

*Assume that 1 user generates 2 requests or transactions to the server per 1 minute.
