You can use the following commands to identify potential bottlenecks, observe the type of NFS operations taking place on your system, and tune NFS-specific parameters.
TheÂ nfsstatÂ command displays statistical information about the NFS and the RPC interface to the kernel for clients and servers.
This command could also be used to re-initialize the counters for these statistics (nfsstatÂ -z). For performance issues, the RPC statistics (-r option) are the first place to look. The NFS statistics show you how the applications use NFS.
