The upcoming patch release of Deno uses 2.3x less memory than Bun running the compiled executable of this example on Windows (70 MB vs 160MB after 60 seconds).

I heard Deno is built in Rust? What optimization changes were made to decrease the memory usage in this upcoming patch? Less .clone() 's ? (genuinely curious)

The current Deno 2.0.2 outputs 104 MB after 60s, so this is about a 33% reduction from that. The new savings come from more efficient memory management of the module sources.
