Does this look right for a Dual-PIII, no load other then the operating
system, idle disk *only* being used for the tests ... just seems low to
me:
Writing the 232 Megabyte file, 'iozone.tmp'...14.273438 seconds
Reading the file...3.328125 seconds
IOZONE performance measurements:
17043521 bytes/second for writing the file
73095100 bytes/second for reading the file
==============
full configuration fo that machine can be seen at
http://atelier.acadiau.ca, but the basics are:
=========
ahc0: <Adaptec 2940 Ultra SCSI adapter> port 0xa800-0xa8ff mem 0xe0000000-0xe0000fff irq 10 at device 11.0 on pci0
ahc0: aic7880 Wide Channel A, SCSI Id=7, 16/255 SCBs
===========
da1 at ahc0 bus 0 target 1 lun 0
da1: <WDIGTL WDE9180 ULTRA2 1.30> Fixed Direct Access SCSI-2 device
da1: 40.000MB/s transfers (20.000MHz, offset 8, 16bit)
da1: 8727MB (17873040 512 byte sectors: 255H 63S/T 1112C)
