Any reason not to do CPU COSTING as described by Jonathan Lewis?
"You can enable cpu_costing simply by collecting system_statistics for an
appropriate period of time with the dbms_stats package. This records in the
table sys.aux_stats$ values for:
assumed CPU speed in MHz
single block read time in milliseconds
multiblock read time in milliseconds
typical achieved multiblock read."
