Improving latency for one scenario can degrade it in another. Objections to the comparison are legion. What are its goals?

Sometimes developers only care about speed. Some will claim that any type of RPC communication ends up being faster (meaning it has lower latency) than any equivalent invocation using asynchronous messaging. It’s less of an apples-to-oranges comparison and more like apples-to-orange-sherbet. So we’ll just use “RPC” for short.
