Deno packs a lot in and V8 is pretty big to begin with. It makes sense to me that a Go binary will be leaner in pretty much every metric than a Deno script. I think the win with Deno is the JS ecosystem and the situations where JSs dynamicity is an advantage. Sometimes (often times, in my own estimates) that's worth double the memory usage and 20% the raw CPU performance.
