Is it slower if you access a record through ALT INDEX as compared to Primary INDEX? Why?..

Answer / scott

If you are reading more than one record it is potentially
slower using the ALT INDEX. The reason is the primary index
is clustered, so you do not perform an I/O when you get the
next record in the index.
