or AutoFS in your

environment?

• Troubleshooting

Automount and AutoFS are generally not considered daemons used for

performance reasons. In fact, in performance sensitive environments, the use of

any automounter should be carefully scrutinized as it will typically add some

amount of overhead to the NFS client. The decision whether or not to use these

products is typically made by system administrators who are familiar with the client

environment. For those administrators who do choose to use one of these products,

there are several performance and behavioral issues to consider.

This section describes how the classic automounter differs from the newer AutoFS

product in terms of functionality and performance. Also described are the many

configuration-related factors that can influence automounter performance. A

discussion on whether the classic automounter or newer AutoFS is a better choice

for your environment is included. Finally, a troubleshooting section describes the

methodology used to investigate most automount and AutoFS related problems.
