My understanding from the mysql docs is that indexing is to be used primarily for speeding queries on often used tables. This particular table is to be queried quite a bit , but almost entirely using the priamry key. So, I assumed that making the primary key an index would speed table searches. However, it prompted me to ask the question, are primary keys already optimized for some sort of indexing and searching? So then I emailed the list.
