Those particular numbers all look to be from fairly dated hardware.
With somewhat modern hardware (5 Seagate Cheetah Ultra2 drives on two
Ultra2 channels on one 3950U2b Adaptec controller all in a RAID0 array
in a PII 266 box with 128MB RAM) I'm seeing numbers like these:
2.0.36UP:
-------Sequential Output-------- ---Sequential Input-- --Random--
-Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks---
MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU
512 12020 98.2 65325 89.0 14788 50.0 14585 94.2 65283 86.7 255.1 5.5
512 12018 98.2 64312 87.8 14975 49.8 14707 95.3 65065 85.4 251.4 5.2
512 12041 98.2 66525 91.7 15027 50.2 14801 95.6 63949 86.2 258.8 5.6
The numbers I have for 2.1.131 so far are all SMP numbers and so can't
be compared against the 2.0.36 numbers. I plan on getting some UP
numbers for 2.1.131 as well before too long.
