More information please.

Is this a once off insert or a regular operation. If once off, use the
embedded server and local connection (obviously). Turn off forced
writes (for the inital batch insert only, re-enable them afterwards),
disable the indices (again for the initial batch insert only,
re-enable them afterwards). I shouldn't have to say this, but I assume
with these suggestions you would have a working backup taken before
you run the batch.

Like Ann said, any triggers? 190 inserts per second seems a bit slow
to me. Is it really 5 - 10 minutes, or is that figure more an
exageration and what you mean is that it is slow? What sort of speed
are you expecting? Is the input file on the same drive as the database
file? If so, you could be overloading the I/O capabilities of your
machine.

Depending on your answers to all the above, it could be the speed of
on of the many interfaces you are using. Another option is to use
external tables, fill it using ColdFusion, then run a query that
transfers the data to a table within the database.
