comment Does having an index on a VARCHAR column with a lot of very similar starting values have bad performance
@Mark - The width is varchar(64) We can have up to 7 million rows. We run cleaners on it daily to remove old data. So about 7-10 million on average. I guess the average length of that field is about 20-30.
