How not to structure database-backed web apps: performance bugs in the wild

I once sped up a program by 90% by turning `new String("foo")` into just `"foo"`. The project was still rotten though, so it ultimately didn't matter.

Your example sounds interesting, could you explain more

Are you familiar with Java? If you use just `"foo"`, then the string will be interned and reused. If you use `new String("foo")`, each call creates a new copy on the heap. This call was inside a very hot loop, thus eating almost all the application's runtime.
