You will have output counts from your original unload? Write those down. Use those. Type them into a dataset, side-by-side, if you want.
Evaluate the amount of resources used by that method.
Now, even excluding effort expended on coding, evaluate the resources expended on reading through both files in their entirety to get an equivalent dataset.
Be aware that for any type of reconcilliation a simple count is useless if that is all you have.

Is this a one-off exercise or a daily/weekly/monthly task? If a regular task then get the dataset creation programs to write the totals either to a trailer record that sort can easily extract or write the count to a common file. If a one-off exercise then it is proably as easy to get the record counts manually as it is to run each dataset through sort individually to get the count.
