Hi
About your question in Oracle Group :
Look, almost 50% of the cpu's work time is related with disk i/o, so you must to check
how much disk activity are there in your plattform. If you find a high level disk activity maybe your Oracle SGA is a little small, in this case you must to increase the parameter shared_pool_size about 20 or 30% and try a again.
Hope this help you
