Interesting post about how the author with the help of the Go community
has got better performance than C++ version.
"After optimizations, the Go ray tracer was 8.4 % faster than a
functionally equivalent C++ version when rendering a 4.2 MegaPixel image
using a single thread. With multi-threading enabled, the performance gap
widened to 76.2 % on a 8 Core machine."

The only honest conclusion of this exercise that I can see is that a
program with a superior algorithm compiled with a non-optimizing
compiler (6g/8g) can beat a naive program compiled with an optimizing
compiler (GCC). That's not an interesting conclusion.
