I think you misread the title. The title implies that it took little to no work to port it to this new framework, not that it runs in an instant.
"A fire built around a wad of kerosene soaked rags starts instantly."
Does that sentence suggest that kerosene starts rags to you, or that kerosene soaked rags help start fires instantly?
English, being a very complex language, can have the same sentence mean multiple things as well depending on how you interpret the context. There may be better ways to phrase something to remove ambiguity, but the title as presented could be read both ways.
