Actually, good point - especially since I tested the inside the loop C# with 100,000,000 records as well. ( 4.4 seconds ) but only did it once..

Though a good deal is too strange to be believed, nothing is too strange to have happened.
- Thomas Hardy
Half the harm that is done in this world is due to people who want to feel important. They don't mean to do harm-- but the harm does not interest them. Or they do not see it, or they justify it because they are absorbed in the endless struggle to think well of themselves.
-- T. S. Eliot
Democracy is two wolves and a sheep voting on what to have for lunch.
Liberty is a well-armed sheep contesting the vote.
