I tried this at your suggestion (though it didn't look like it was analyzing
as there were not status on the tables).  This didn't help.  I even tried
turning off archiving and no joy.

Sounds strange and I can't give you any good reason but I do have one idea.
Have you tried:
analyze=n

If you take RAC out of Oracle you get OLE!  What can this mean?

Oracle 8.1.7 on Solaris 8

I am testing and upgrade from 7.3.4 to 8.1.7.  Because the test server is
solaris 8, and I can't find the patches for 7 anymore, I am trying to
upgrade via an export and import.  Besides, the DB is small - less than 2G.
The export was done with compress=n.  There are 200+ tables to be imported.
It is taking 3+ minutes per table for the import, even on tables that have 0
rows.  (Though it does take longer than that for the few tables with over
50K rows).

I have tried:
  1)  Simple import.
  2)  Import with indexes=n
  3)  Import with table and constraints (but not indexes) pre-created and
indexes=n ignore=y
  4)  All of the above with the buffer set to 8M  (This actually slows the
import down, taking 5+ minutes per table).
  5)  Increasing the sort_area_size for the DB to twice as large as it was
and trying the above.

In looking at how long it takes, the table imports in a second or less, but
it takes 3 minutes + to start the import of the next table.  I'm not sure
what it is doing for 3 minutes after the table imports.

Does anyone have any ideas how I can speed this up?  10 hours to import a
2G. DB is extreme and unacceptable.

TIA.

Terry
