With a small tweak to how we build the JS objets, I can make the JS version outperform the CPP version in JSC as well:

chromium-mac-js2: 191981.8 runs/s
apple-mac-js2: 472447.4 runs/s

The difference is that js2 uses createMirrorDOMNode() to add the properties in the same order for every JavaScript "DOM node."  (Attaching updated perf test shortly.)
