My recollection is that 3x3 is a goal to be 3x faster than Ruby 2.0–presumably many of those gains have already been realized, so best not to depend on tripling _current_ performance.

Yeah, the NES emulator that's one of the benchmarks is about 1.8x faster so far, so only another 1.6x to go on top of that.
