Some of those loads are unexpected. Can you verify that /O2 optimization is on (since release builds can, in theory, have optimizations off).

Yes - one of the first things I checked - I've tried it with /O2 and /Ox

Same result both times.

If you have the time to play with it some more ... I wonder, does gcc or clang or icc do a better job?

Unfortunately I don't have any of these compilers ready to use at the moment, but I may try some of them in a week or two.

ICC is pretty spectacular (and sometimes awesome!) at optimization.
