How many indexes do you have on the table columns?

No Blobs, No Longs, No BFILE, only VARIANT, FLOAT AND INTEGER (14
fields), direct load. Pentium IV, 2,5 MHz. Then... What is the
problem?

Thank you,

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.
