Basically you would need to post much more information for anyone to come up with a valid answer.
For a start you'll need to run statspack, generate a statspack report, and submit it to www.oraperf.com
You say there is a major difference in performance, but you don't specify it in any fashion, nor do you provide any information of the hardware and/or on disks involved. Chances are very high you are comparing apples and pears.
So 'Does anyone know' No, of course not, as no one on this forum is clairvoyant and we aren't looking over your shoulder.
