problem with mult datafiles and local mng tblspaces

I have a 9.2.0.3 DB running on AIX 4.3.3 An application running on W2K using SQLLDR to load approx 6g of data using local managed tablespaces
ie..
CREATE TABLESPACE PARENTDAT

	DATAFILE '/vol01/oradata/e450dev/parentdat01.dbf' SIZE 2000M REUSE,


	'/vol01/oradata/e450dev/parentdat02.dbf' SIZE 2000M REUSE,

	'/vol01/oradata/e450dev/parentdat03.dbf' SIZE 2000M REUSE,

	'/vol01/oradata/e450dev/parentdat04.dbf' SIZE 2000M REUSE

	EXTENT MANAGEMENT LOCAL UNIFORM SIZE 1M
	NOLOGGING
	ONLINE;

It was taking 8 hours to load this data
1) copied the data to the AIX box and ran SQLLDR local to the DB and received similar results
2) changed the tablespace to contain 1 8g datafile 3) ran SQLLDR from the W2K machine ..completed in 30minutes

Also
ran the same test on AIX 5.1 running oracle 9.2.0.3 and obtained the same results.

I really would like to be able to create the tablespaces with multiple data files but it seems whenever I add a datafile the performance of the load degrades.

Any ideas??

Thanks in advance
John
