Yeah. I had not tried all the compiler options. Using -fasm is slower on this
for me as well.  I suspect that since your code will beat the entries that have
been posted so far, so I thin you should submit it.

Also, could you explain how to check the Core (un)boxing in a note on the (new?)
wiki?  I would be interested in learning that trick.
