Raj,

One statement caught my eye:
  The buffer cache hit ratio is 99%

My bet is you've got some very inefficent SQL. As is typically the case, application tuning has the biggest effect on performance.

I'd suggest checking out Cary Millsap's excellent paper "Why 99% Database Buffer Cache Hit Ratio is NOT Ok" (available with free registration):
