I'm curious about the 10x via implementation in Go - couldn't it have been realized otherwise? Finding the hotspots, reimplementing them using better algorithms, if necessary move a few critical paths to native etc. Or even improving the JIT itself which might benefit all programs. Just wondering because I wouldn't think that the JIT-overhead was that much that you could gain 10x just reimplementing in Go (or C, assembly etc)... that is something I would only have expected if going from an interpreted context.

hjalsberg has explained this in some interviews. roughly 3x speed up from going native, another 3-4x speed up from being able to actually do effective multi threading
