Disk IO

The disk IO tests are invoked by the -disk switch. These tests consist of reading and writing bytes through single threaded calls.

The behavior of disk IO tests are controlled by the following suboptions:

• size
• read block
• write block
• file
• iterations

size=<n> where <n> is the number of bytes the operation read/write. This suboption measures the speed at which bytes can be read/written depending of the size of the file. This measures the effect of file fragmentation depending on file size.

rblock=<b> where <b> is the size of each read. This suboption indicates that the file created will be read in chunk of <l> bytes.

rblock=<b> where <b> is the size of each write. This suboption indicates that the file created will be read in chunk of <l> bytes.

file=<filepath> where <filepath> indicates where the file will be created.

iteration=<i> where <i> indicates the number of times the test is repeated.
