= Description =
Bonnie++ is a filesystem benchmark that measures basic speed of several
operations, including data read and write speed, the number of seeks per second, and the number of file metadata operations per second.

Bonnie uses the following test variables at runtime:
* BENCHMARK_BONNIE_MOUNT_BLOCKDEV - name of block device where filesystem to be tested in located, or "ROOT"
* BENCHMARK_BONNIE_MOUNT_POINT - directory name where the filesystem should be mounted (if needed), and the tests run.
* BENCHMARK_BONNIE_SIZE - specifies the size, in megabytes, of the files used for IO performance measurements
* this is the parameter to the -s command line option
* BENCHMARK_BONNIE_RAM - specifies the size of the board's RAM in megabytes, or "0" if ram size sanity checks should be disabled
* this is the parameter to the -r command line option
* BENCHMARK_BONNIE_NUM_FILES - is a colon-separate 4-tuple indicating the number of files, the file max size, the file min size, and the number of directories to spread the files into, for metadata tests
* the default value, if not specified is: "16:0:0:1". This results in 16K files with maximum and minimum size 0, in 1 directory.
* BENCHMARK_BONNIE_ROOT - should be set to "true" if the bonnie should try to execute as the root user on the board.

= Notes =
Notes: If a test executes too quickly, bonnie does not report the result, and instead produces '+++++'s in the entries for those tests. Specifically, bonnie will emit this if a test result was less than .5 (MinTime in the source code).
If this happens for you, consider using or writing a spec that increases the size of the files, or the number of files used for tests.
