I suspect you're being downvoted because no, you're definitely not expected to have 32GB of RAM. I'd imagine the example just uses a high-end config to show that it's not a hardware issue bottle necking performance (or, rather, not a hardware issue you'd normally run into - e.g. not enough memory, too slow CPU etc). Downvoting seems somewhat over the top, I'd say.
