BAPI commit

hi,

I am using BAPI function modules to upload the date about 500 records into the business partners(BP)

and when I am using BAPI commit function module , it is taking lot of time at this time point, can any one suggest a way where I can increase the performance by changing some code in BAPI commit as I need to upload aroung 10000 records in 2 to 3 hrs time..

Thanks & Regards,

Aruna.
