Bonnie++ is afree softwarefile system benchmarking tool forUnix-likeoperating systems, developed byRussell Coker. Bonnie++ is a benchmark suite that is aimed at performing a number of simple tests of hard drive and file system performance.
Bonnie++ allows you to benchmark how your file systems perform with respect to data read and write speed, the number of seeks that can be performed per second, and the number of file metadata operations that can be performed per second.[2]

The finalCSV output includes the information related to data read and write speed, number of seeks that can be performed per second, and number of file metadata operations that can be performed per second and the CPU usage statistics for the below given tests:
This benchmark is named Bonnie++ because it is based on the Bonnie benchmark written byTim Bray.
