Check out running SQL Loader in parallel -it can be done, and if you distribute the temporary files it creates amongst sufficient devices, you should get performance improvements (though "running it in parallel" is a bit of a misnomer... you basically copy your control file X times and chop the datafile up into X pieces, and fire up X number of sql loader sessions).
