How much will your datafiles grow?

Not used space impacts the performances in no way.

Why do you blame amount of free disk space for high CPU usage?

This does not answer Littlefoot's question.
Who is using the CPU?

Oracle is using 100% cpu .

And why do you believe that the amount of free/used disk space has anything whatsoever to do with that?
