I can't say I've ever heard it recommended as good practice from the standpoint of performance in any specific language I've ever worked with, but I have heard people suggest that you always include an explicit default case in any kind of branching logic. It does seem useless to say default: // do nothing break; in a switch block, but I imagine the reasoning behind it is so that anyone who reads your code can see that you actually thought about what should/would happen if none of the other conditions were true rather than ignoring those conditions.
