Abstract : This report describes a series of experiments to investigate the performance of SCSI disks as seen by the application programmer. The results show a significant performance loss, on the order of 50%, when two or more files are simultaneously read from the same disk. Performance is also reduced when files are stored in an interleaved manner, and when small block sizes are utilized.
