sysbench fileio based disk io benchmark with common metrics
Just another simple wrapper over sysbench fileio to output a table of common metrics.
sysbench fileio will create some files under the current working directory named starts from test_file.0 to test_file.<fileNum> and have a total sum of sizes equal to <fileTotalSize>, so the size of each test_file is <fileNum>/<fileTotalSize>.
iobench.sh will invoke sysbench fileio to do combinations of some common params and convert the human-readable report in its stdout to space separated tuples into stderr for any further summary analysis about the performance of the file system and its block device behind testing pwd.
