The point of this data set and associated queries is to see how fast the
database can do certain types of queries on its own. Some other types
of database implementations automatically do well here due to column
storage and other techniques; the idea is to measure how you can do
without trying to rewrite the app any though. If precomputed aggregates
were added, they'd improve performance for everybody else, too.
