--- Comment #6 from pkb07815 (pankajcabs@...il.com) ---
I have tried with noop, CFQ and deadline, same results.

Io is mainly related to /data partition, which is mounted as :

/dev/sda9 on /var type ext3 (rw,noatime)
/dev/sda10 on /data type ext3 (rw,noatime,barrier=0)

/var mainly has logging part. We have lot of db traffic (postgres) flowing
under /data.
I have also tried writeback instead of ordered (default) for /data.
