21.9 Controlling the Number of Processes Running for Each Service

If a server has multiple CPU's, by default Calendar Server distributes the HTTP Service (cshttpd processes) and Distributed Database Service (csdwpd processes) across the CPU's.

If you want to control the number of processes that run for each service, you can edit the service.http.numprocesses and service.dwp.numprocesses parameters. By default, these parameters are set to the number of CPU's for the server during installation, but you can reset these values. For example, if a server has 8 CPU's, but you want a cshttpd and csdwpd process to run in only 4 CPU's, set the parameters as:

service.http.numprocesses="4"
 service.dwp.numprocesses="4"
