Capacity Planning

Other Services and Activities

If your server is also acting as a Dynamic Host Configuration Protocol (DHCP), Windows Internet Name Service (WINS), or Domain Name System (DNS) server on a local area network (LAN), or as an e-mail and news group server, you must take into account the network bandwidth used by these services when planning your bandwidth budget (as well as your processing budget). If you anticipate heavy traffic, you should move these other services to a different server computer.

When testing new applications, particularly on a site that is actually in service, it’s a good idea to run them out of process, despite the fact that this introduces additional computing overhead. For more information about running out-of-process applications and services, see Data Access and Transactions in this book.
