NFS performance

AIX® provides tools and methods for Network File System (NFS) monitoring and tuning on both the server and the client.

Network File Systems
NFS allows programs on one system to access files on another system transparently by mounting the remote directory.
NFS performance monitoring and tuning
There are several commands you can use to monitor NFS statistics and to tune NFS attributes.
NFS performance monitoring on the server
You should check CPU utilization, I/O activity, and memory usage with the vmstat and iostat commands on the NFS server during workload activity to see if the server's processor, memory, and I/O configuration is adequate.
NFS performance tuning on the server
NFS-specific tuning variables on the server are accessible primarily through the nfso command.
NFS performance monitoring on the client
You should check CPU utilization and memory usage with the vmstat command on the NFS client during workload activity to see if the client's processor and memory configuration is adequate.
NFS tuning on the client
NFS-specific tuning variables are accessible primarily through the nfso and mount commands.
Cache file system
You can use the Cache file system, or CacheFS, to enhance performance of remote file systems, like NFS, or slow devices such as CD-ROM.
NFS references
There are many files, commands, daemons, and subroutines associated with NFS.
