You need to be more explicit.

Things to look at:

How many disks do you have?
How are the datafiles distributed?
I presume tablespaces are Dictionary managed not Locally managed? What SQL is being executed?
Plus lots more!

You should run Statspack to get a snapshot of the system activity, that will point you in the right direction. However, if you need some assistance I'd be happy to look at your system for you.
