Are you talking about using a table to update/insert the other table, or just load those data to tables directly? I have tried SQLLoader in conventional mode and direct mode It gave huge enhancement on loading. Maybe you can try to work on how to load in direct mode, disable triggers, constraints first, enable them after you load it. Or run PL/SQL to enforce whatever you want to complish. That is what I did. I save a lot of time on loading, some improvement on PL/SQL scripts.
Also try load in parallel , spread those tables in different tablespaces on different drives.
Hope it works better.
