Markus,
It worked fine here. And i got a lot of increase in I/O subsystem.
# dd if=/dev/rsd0f of=/dev/null bs=1024k
^C243+0 records in
243+0 records out
254803968 bytes transferred in 4.318 secs (59004868 bytes/sec)
# expr 59004868 / 1024
57621
#
I was getting just 1 MB/s. BTW, this machine i use day by day, and gonna
report if something go wrong.
