      I have some sample data & when uploading 165 user records with this sort of thing:

      username,course1,course2,course3,course4,course5,group1,group2,group3,group4,group5
      myusername,9.1,9.2,9.3,9.4,9.5,9H,9H,9H,9H,9H
      myusername2,9.1,9.2,9.3,9.4,9.5,9H,9H,9H,9H,9H

      Its costing 16,000 database queries. This makes the upload unusuable.

      Need to investigate and improve what is causing this.
