This paper deals with file access performance variation measurements and analysis of I/O intensive applications (video on demand, multimedia, data bases for example) accessing large sequential defragmented files on Windows systems. A global performance study on different configurations (different versions of OS, file systems and disk technologies) shows an I/O throughput drop by a factor 3 depending on the request size and up to a factor 10 depending on the specified access mode. We also observed that the global performance pattern remains approximately the same. This lead us to perform more specific and accurate measurements to explain the dramatic performance drops and glitches. We evaluated and identified the exact functioning of the I/O system for the different existing access modes including disk functioning, and file system cache algorithms [9]. Finally, we give programmers guidelines to get optimal performance for Windows I/O system depending on the application constraints'.
