The key difference is the IDE vs SCSI-2 hard-disk. I only use iozone 1, just to be consistent and make the test more realistic. Most applications do not need more than 1 Megabyte of sequential access.. 386/25 no cache, Maxtor 7120 200Mbyte Hard-disk runnig 386bsd,patched to Terry's beta. Writing the 1 Megabyte file, 'iozone.tmp'...3.333333 seconds Reading the file...2.483333 seconds IOZONE performance measurements: 314573 bytes/second for writing the file 422245 bytes/second for reading the file The test completed too quickly to give a good result You will get a more precise measure of this machine's performance by re-running IOZONE using the command: Julian's machine, 486/50, Bustek SCSI-2 1.3G hard-disk(?) IOZONE performance measurements: 683854 bytes/second for writing the file 499322 bytes/second for reading the file The test completed too quickly to give a good result You will get a more precise measure of this machine's performance by re-running IOZONE using the command: -- Othman bin Ahmad, School of EEE, Nanyang Technological University, Singapore 2263.
