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.
