Minor sample update

[ncave]

• Minor update of the run-time performance of the RayTracer sample (now 20% faster).

On a side note, interestingly and anecdotally, looks like MS Edge is pulling ahead and is now at least 10-15% faster in executing JavaScript than Chrome and Node.js, for whatever reason. And Firefox is still way, way slower, unfortunately.

Thanks @ncave! Interesting, I'd assume Edge is using now the same V8 engine for JS as Chromium and Node.js but maybe it adds some optimizations on top.
