Since you've said that the 800K records data won't change for the life of the database, I'd suggest linking to the text file as a table, and skip the insert altogether.

If you insist on pulling it into the database, then 800,000 records in 1 minute is over 13,000 / second. I don't think you're gonna beat that in MS Access.

If you want it to be more responsive for the user, then you might want to consider loading some minimal set of data, and setting up a background thread to load the rest while they work.
