True dat!!!

The point we are making here is that 1:08 seems pretty slow for whatever you are doing unless the row count is in the millions.

This table has about 9,000,000 recs.
However, when I added clustered index the time dropped to 0:32
Is it still limping?

Depending on what your actual query looks like that doesn't sound horrible to select 9 million rows.
