To benchmark the disk seek and transfer performance in FreeBSD, you can use the bonnie++ utility. Bonnie++ is a disk benchmarking tool that measures various disk performance metrics, including seek rate and transfer rate.
To install Bonnie++, use the pkg command:
pkg install bonnie++
This will install Bonnie++ and all of its dependencies.
To use Bonnie++, run the following command:
bonnie++ -d /mnt/disk -s size
Replace /mnt/disk with the mount point of the disk that you want to benchmark, and size with the size of the test data in megabytes. For example, to benchmark a disk with a mount point of /mnt/disk and a test data size of 1024 megabytes, you would use the following command:
bonnie++ -d /mnt/disk -s 1024
This will run the Bonnie++ benchmark and print the results to the console. The results will include the seek rate and transfer rate for the disk.
It's important to note that the results of the Bonnie++ benchmark may vary depending on the configuration and usage of the system. You should run the benchmark multiple times to get an average performance measurement.
You can also use other disk benchmarking tools, such as hdparm or dd, to measure disk performance in FreeBSD. Consult the documentation for these tools for more information on how to use them.
