C# developer: static typing and precompilation make my language really fast! *writes service that makes 50 synchronous database calls for every request*

I once worked with a guy that was tasked to make a simple index page of about 100 records. Somehow that page ended up making over 10,000 Db calls on each load. Imagine the horror on the faces of the rest of the team when we stepped in to help because the client was complaining of long load times.
