Not really (at least yet, I think). This simply bundles the Deno binary and the script (I think the pre-compiled, as in TypeScript -> JavaScript, then possibly as pre-compiled AST). This is why the output binary size is the original Deno binary + the script size (roughly).

So it's functionally equivalent to running using deno test.js

Correct. We are currently working on reducing size for these `deno compile` binaries. From preliminary testing we think we can reduce size by around 60%.

Regarding speed, we are investigating V8 snapshotting of the user code, which would give it a great boost in startup time. Actual runtime performance would be the same.

Would it be theoretically possible, to end up using this as sort of a scripting language for rust or whatever. I'm imagining Deno somehow getting complied down to Rust and then running at Rust speed.

I basically want low level performance without writing in a difficult language

No this is not possible. JS is too dynamic for that to work.
