How does this increase speed?

I see there is like one paragraph on how engines can get the entire module graph for parallell bytecode generation, but can you really expand on this because I am having a little trouble understanding how exactly that could significantly boost performance.

Well, that paragraph is quite speculative. I feel uncomfortable making that the driving motivation for the proposal. I'd rather focus on how this makes it more possible to use native ES modules, which otherwise need to be transpiled away.
