I think you're comparing apples and oranges. The SQL program reads data from disk and groups that, the perl programs groups data that is already in memory. When you put the perl program in production it should also read the data from the database.

Do I understand correctly that all that you do is something like: 

  select a,b,c,d,count(*)
  from x
  group by a,b,c,d

Or do you also sum subgroups?

Can you please show the SQL query?
