By "Loading data" I am implying: "psql -U postgres -d somedatabase -f sql_file.sql".  The sql_file.sql contains table creates and insert statements. There are no indexes present nor created during the load.
COPY command: Unfortunately I'm stuck with INSERTS due to the nature this data was generated (Hadoop/MapReduce).
Your basic options here are to batch the INSERTs into bigger chunks, and/or to split your data file up so that it can be loaded by more than one process at a time.  There's some comments and links to more guidance here at http://wiki.postgresql.org/wiki/Bulk_Loading_and_Restores
