What i noticed was , for transfer size less than 512K there was a better perfomance for read and write than larger transfer size. But for file size the readings didn't seem to exhibit any particular characteristics. Does the file size play any impact on the performance characteristics. I understand that if the file size is small, caching plays an impact. Please let me know your opinion. Thanks Jayshankar
