You can't test performance in a Playground, and most of all not compile performance. Playgrounds do a lot of extra work to display "(9999 times)" in the right-hand column. Playgrounds also don't really have a separate "compile" step that you can separate from execution. And they don't optimize the code. There's no part of performance that you can evaluate in a Playground.

When I compile this with swiftc it takes less than half a second. It runs in less than a second.
