Java performance urban legends

Pretty good article on Java performance "urban legends".

In summary...

  • Urban performance legend #1: Synchronization is really slow

  • Urban performance legend #2: Declaring classes or methods final makes them faster

  • Urban performance legend #3: Immutable objects are bad for performance

Thanks to Demitrious for the link.
