Thanks a lot for your help... all of you.

For me write speed dont matter much as we run a nightly batch process to update the database and the users only use the database to query it from the web site.

But after running scripts I see that there is a lot redo log latch contention and also contention for rollback undo headers. Should I ignore them because of the fact that its the read speed which counts or should I do something to fix it.

I must mention here that I have 2 logical partions on a RAID 5 machine all across the same set of hard drives ( 4 ).

Please suggest.

Thanks
