SubjectRe: NCR benchmarking

Hi Alexander!

As promised, I send to you some bonnie results.

-------Sequential Output-------- ---Sequential Input-- --Random--
-Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks---
Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU
8xx TQ4 100 3938 75.7 3484 20.7 1704 19.2 3546 62.2 4338 20.7 54.9 2.7

Hardware:
P133 / Tomcat I / 512KB PB / 32MB EDO / NCR53C810 / IBM S12

Software:
Linux 2.0.3

Scsi features:
10MB/sec sync transfers, disconnection allowed, tagged queue when possible.
(TQ0 means tagged queue not used)

Filesystem:
Fresh 330 MB 1K block ext2fs on the last 1/3 of the disk area.

Conditions:
Just booted, cron and lpd killed, 1 interactive user.

Comments: none

Gerard.
