2.5 million records takes 2.5 hours? Man, you're doing something seriously wrong. How many MEMO fields do you have? What are you loading them into? Blobs? Longs? BFILE? As for SQL*Loader, if you were doing parallel and direct load into a NOLOGGING table, and if the stuff you were loading consisted of short numeric/textual fields, the whole thing would be loaded in less then 10 minutes on a 400 MHZ PC using the sorry excuse for an operating system, produced near Seattle, WA.
