979966Dec 14 2012 — edited Dec 17 2012

I am having Slow IO performance issue in Oracle Linux 5.8 uek 64bit kernel for SATA Disk connected via SAN,
and I have tried using dm-multipath and LVM, nep,

and the same SATA disk does not have any issue with RHEL5.8 32bit, with RMAN Backup it is 8-9 hours backup duration,
but in OEL5.8 64bit uek it takes 15Hours to complete RMAN Backup of Oracle R12 DB Backup.

Please help me.
