The speed you are seeing is not typical (I think, since you are not
specific here). I recently moved records into an IB database where the
source was another IB database (not a text file) on the same server. This
was run on the server itself, ForcedWrites=Off and no indexes (just a
primary key constraint), The process (Delphi/5+IBO) easily transferred
2000 records per second (declared record lengrh approx 500B). The server
has 2 processors (850MHz) and fast disks (15000rpm) running Win2k (with
mirrored disks), and the processors were not utilized 100% (more like
50-60% IIRC).
Your other problem may be a show stopper, but importing into IB should not.
