Linux penguinBonnie++ is a disk and file system benchmarking tool for measuring I/O performance. With Bonnie++ you can quickly and easily produce a meaningful value to represent your current file system performance.

Before using Bonnie++ make sure that you have it installed on your system. In Ubuntu, use apt-get to install the bonnie++ package.

Run the bonnie++ command  with the following attributes:

  • [TEST_LOCATION] – is where bonnie++ will create the benchmark operations.
  • [TEST_SIZE] – the size of the test file – this should be greater than double the RAM in your system.
  • [TEST_NAME] – this is simply a label which will be written out with the results.
  • [TEST_USER] – the user who should perform the test. This is not required if you are not running as root.

For example:

The easiest way to understand the results of a bonnie++ test is to run the output  through the bon_csv2html utility. This perl script uses the bonnie++ results and generates a HTML page which you can later open with your web browser.

Copy the last line of the bonnie++ output into the echo command to replace [RESULTS] and alter the [OUTPUT] path to point to where you would like to save your results.

Example command:

Finally open the output file with your web browser.
