How many work processes should be configured for each instance ?

Dears,

General, how many work processes you configured for your each instance?

For example, how many dialog processes , background processes , update processes will be configured respectively in your Central Instance

and Dialog Instance ?

Currently, our CI configured 80 dialog processes and 6 batch processes and 6 update processes, and DI configured 50 dialog processes and 10 batch processes and 5 update proceeses .

I want to increase some background processes in CI , but I don't konw if it will impact the system performance, what's the rate between Dia:Batch:Upd ?

Thanks,

Michael
