Performance and the size of the index file.  My reference is for Drupal 
5 and I do not know what may have changed for Drupal 6 yet but there 
are a number of duplicated indexes on some of the tables.  A column 
might be used as the first position in combination with another column 
to create an index and also be declared an index alone.  This becomes a 
duplicate index and isn't needed.  Some tables do not have unique or 
primary key identifiers a big performance hit.
