nhfsrun Command in Linux
The nhfsrun command in Unix, Linux is used to execute nhfsstone (a benchmark tool for NFS performance) with a range of different loads. The results of the benchmarking run are saved into a file named run.<suffix>. The <suffix> argument allows you to specify a suffix for the result file, helping differentiate between different runs or configurations.

Syntax of nhfsrun Command
The following is the general syntax for the nhfsrun command −
nhfsrun <suffix>
The nhfsrun command runs nhfsstone with a range of different loads. The results of these runs are stored in a file named run.<suffix>. Each run generates a set of performance metrics that are saved in the output file.
Example of nhfsrun Command in Linux
In this section, we'll walk through a practical example of using the nhfsrun command to benchmark an NFS server,
Running nhfsrun
Let's say you want to run nhfsstone over multiple loads and save the results with the suffix test. You can use the following command to perform the operation −
sudo nhfsrun test
This command will create a file named run.test that contains the results of the nhfsstone runs under different loads.
Conclusion
The nhfsrun command is a useful tool for benchmarking NFS performance in Unix and Linux environments. The flexibility of the <suffix> argument allows you to easily organize and differentiate multiple benchmarking runs.
Whether testing configurations or monitoring server performance, the nhfsrun command offers a straightforward approach to collecting and analyzing NFS performance data. However, you should take into account that tools like nhfsrun are considered outdated and may not be compatible with modern systems. These tools were designed for older Unix systems and may not function properly on contemporary Linux distributions without modifications.
Compatibility issues could arise due to changes in system libraries, kernel versions, and other dependencies.
For more modern alternatives, you might consider tools using like fio (Flexible I/O Tester) for benchmarking, or nfswatch for monitoring NFS traffic. These tools are actively maintained and widely used in current environments.
