In general, to speed up the database side, you want to

• Minimize the times you connect to the database. So, you cache connection.
• Minimize the times you compile SQL statements. So, you use stored procedures.
• Minimize the search time to the appropriate row(s). So, you use indices.
• Minimize the need to disk access. So, you let the database use as much memory as possible for caching.
• Minimize the number of pages involved. So, you keep your rows as small as possible, possibly using various tables instead of having many columns.

Your question is very general, and without knowing the database server, and the structure of the database, there's not much you can say. A method that's faster on one server, could be slower on another.

Not that any of this has anything to do with Perl.
