Hi There,
I've just decided to keep my list of bonnie tests running. I haven't
pulled the latest changes yet, as CVSUP is basically a day behind
from cvsup.za.freebsd.org.
Here is what I have so far:
First committed version of ATA
-------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
ATA 64 3237 69.0 2913 14.0 1409 9.4 2951 59.3 3043 11.6 55.9 2.4
WD 64 2556 54.5 2902 13.3 1457 9.7 1987 40.3 3082 13.2 59.1 2.0

ATA-noX1 128 3221 68.5 2860 13.4 1169 7.6 2961 58.4 3038 12.2 54.2 2.3
ATA-noX1 128 3169 68.2 2933 12.8 1222 7.8 2944 58.1 3081 12.1 57.8 2.4

After CVSUPing changes from 4/3/99 (before UPDATE-2 heads up message)
All tests : freshly booted, no X
-------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
ATA2 128 3140 67.6 3023 12.0 1175 7.5 3057 58.8 3068 8.6 56.3 2.0
ATA2 128 3122 67.4 3008 11.9 1161 7.2 3121 62.6 3189 9.1 57.5 2.1
ATA2 128 3125 65.9 2981 11.8 1177 7.1 3064 60.2 3189 9.6 56.5 2.1
The only significant diference is on Sequential block inputs and random
seeks where, notably the CU times have gone down. (I have taken no
account of other changes in the kernel.)
Geoff.
