Galileo

Galileo uses a raw partition to perform its measurements to avoid file system overhead.

Measurements are taken at 2K, 4K, 8K, 16K, 32K, and 64K blocksize requests.

Sequential I/O results are displayed in megabytes/sec. Random I/O results are displayed

in IO/sec.

Please refer to Galileo Overview in Appendix B for more information on the Galileo tool.
