Bonnie++

Bonnie++ is a disk IO benchmark utility that allows easy IO performance testing from command line without dependencies to other packages. See further details here bonnie++, here man-page, and here some result explanations

• Installation

1. download the tar from this page Bonnie++ v1.96
2. untar it in your device
3. run install_bonnie.sh as root in the same directory where you untarred the package

• Running tests with bonnie++

as root type following to start the standard test:

bonnie++ -u 0 > test_result

to view the result:

cat test_result

or if you don't need to store the result, just do

bonnie++ -u 0

Example run

Nokia-N900:~# bonnie\+\+ -u 0 > bonnie_emmc_1

Tips

• Testing conditions
  • To achieve somewhat comparable results, let the device boot up fully before running the test
  • Don't do anything else during the test, as this could impact the result.
• The "bon_csv2html" for ARM in the tar does not seem to work in MeeGo
  • One can probably use also the x86 version to create the html pages from the CSV line at the end of the result output...

TODO

1. Do an RPM package from Bonnie++ (current package is just cross-compiled binaries put manually in a tar...)
