You probably want to run dbms_stats with a gather_fixed_stats -  Like
Nail said there are some performance issues with RMAN, Export, Expdp
etc.  -  if your high-cpu queries show a lot of selects against
$HIST_HEAD then this can help.

 

We run this as a standard procedure, and it helps to stop / start the
database although flushing the shared pool -might- help.
