NFS Tuning

The default operating system and network settings do not provide

optimal NFS performance. Improvements can be made by modifying

certain operating system parameters and making adjustments to the

network components.

NOTE: When tuning NFS, it is important to consider your workload and

environment. It is up to you to determine the best settings for

optimizing NFS performance. However, the changes described in

this section may provide a better general starting point for NFS

operations than the default settings on an untuned system.

Tuning Overview

The following diagram shows three areas of the system that affect NFS

performance: the kernel, the network, and NFS clients.
