No worries. :)

With this import you're doing, is it something that will be repeated a 
lot
with the exact same data set, or is this a once off thing?

If it's something that'll be repeated a lot (maybe part of some 
automated
process?), then it might be worth making a backup / snapshot / something
of the database after the import has completed.

With a backup or snapshot in place (depends on the storage you're 
using),
you could potentially load things from that backup / snapshot (etc) 
instead
of having to do the import all over again each time.

Regards and best wishes,
