Read, comprehend, and apply everything in Tom Kyte's and Jonathan Lewis's books.
Set SPEED=REALLYFAST in your init.ora

Generic questions beget generic advice.
No version.
No indication of transaction volume, size, type, etc. No PL/SQL
No explain plan generated with DBMS_XPLAN No profile generated with DBMS_PROFILER

We don't know whether your PL/SQL is calculating the trajectory of the Mars orbiter, loading music DVDs as BLOBS, or part of an ERP application.
