How much does performance differ when doing a SQL join on a key that is a standard int vs a varchar(200) if one table has 6mil records and the other table has 4mil? I'm using MS SQL Server 2016 and most always I use standard int columns for my primary and foreign key relationships, but we have a specific business case that needs to join via a varchar(200) and I just want to know what to reasonably expect.

Thanks!
