Network Performance: Busy Servers
One common source of network performance problems is servers that are overloaded with too many duties. Just because modern network operating systems come equipped with dozens of different types of services doesn’t mean that you should enable and use them all on a single server.
If a single server is bogged down because of too much work, add a second server to relieve the first server of some of its chores. Remember the old saying: “Many hands make light work.”
For example, if your network needs more disk space, consider adding a second file server rather than adding another drive to the server that already has four drives that are nearly full. Or better yet, purchase a file server appliance that is dedicated just to the task of serving files.
As a side benefit, your network will be easier to administer and more reliable if you place separate functions on separate servers. For example, if you have a single server that doubles as a file server and a mail server, you’ll lose both services if you have to take down the server to perform an upgrade or repair a failed component.
However, if you have separate file and mail server computers, only one of the services will be interrupted if you have to take down one of the servers.
