Disk mfr?
rpm?
seek/access times?
diskperf -y set already?
CPU,I/O, or diskbound system?
log buffer size? log file size?
what else is on the "separate" disks? anything?
separate disks share a controller?
select event, time_waited from v$system_event order by 2 desc; results?
just a few questions that come to mind....

Hi all,
I am testing out Spotlight on Oracle from Quest Software. It is telling me
that my log writer process is slow. What it looks like it is saying is that
most disks take about 20ms to right the data and mine is taking on average
about 40ms. I don't know why, they are scsi drives and there isn't that
much stress on the syste. Anyway, I moved the redo logs to seperate disks,
but I fear I may have made an error. Instead of moving each "group" to
seperate hard disks, I moved the members of each group to seperate hard
disks. Anyway, I am wondering if anyone has advice on this problem.
Sincerely,
