Which is more efficient, a switch statement or an if else chain?

The differences, if any, are likely to be slight. The switch statement was designed to be efficiently implementable, though the compiler may choose to use the equivalent of an if/else chain (as opposed to a compact jump table) if the case labels are sparsely distributed.
Do use switch when you can: it's certainly cleaner, and perhaps more efficient (and certainly should never be any less efficient).
