Gopal I am not using RAID05.I am using mirroring.In this case read may be slower but write would be faster.I have RAM=4GB AND each partition is 17gb.The log files and data files are in same disk.This could be one of reason.But the datafile which is most frequently used are on other partition. Hope this will help u to know hardware architecture Thx -Seema >From: "K Gopalakrishnan" <[EMAIL PROTECTED]> >Reply-To: [EMAIL PROTECTED] >To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> >Subject: RE: PERFORMANCE question? >Date: Mon, 04 Feb 2002 12:45:27 -0800 > >By any chance you have your redo logs on RAID05.
