I would have liked to have seen how the author measured the hot spots in the graph. It wasn't immediately obvious to me that the `WriteToUDP` function was taking up a significant portion of the call. Another thing that is omitted is what type of buffer was used. I'm assuming it was a `[]string` slice but why not use a `sync.Pool`?
