If the scoring scheme works the same as the results he shows on the site (higher is better), then V8 is still far faster than QuickJS. Which wouldn't be all that surprising since the V8 folks have spent hundreds of thousands of man-hours on optimization and JIT magic, which is something that would be hard to duplicate, to say the least, in a ~1.5MB all-interpreted engine.
