SubjectYet More CMD640

[Compare linux 2.0.0 performance: 3.38MB/sec]

Here are the results from cmd640.c Version 0.91, both after a cold start.

First with the parameters ide0=autotune ide1=autotune:

Performance

/dev/hda:
Timing buffer-cache reads: 32 MB in 1.39 seconds =23.02 MB/sec
Timing buffered disk reads: 16 MB in 10.54 seconds = 2.42 MB/sec

Dmesg [SCSI errors due to missing disk in easy drive ;)]

by the way, e2fsck repaired the disk in a fly.
Hope you can figure this out,
