If you set the value to -1, the RPC server calculates the number of RPC pool servers to start up. The RPC server calculates this number using the
MAX_USERS_PER_PROCESS value and the number of users held in the iProcess Engine. For example, if there are 800 users and
MAX_USERS_PER_PROCESS is set to
40, then 20 RPC pool servers will be started.
If the value is set to 0, pool servers are started up on demand as users log in. This can slow the login process because users have to wait for the processes to be started.
