I've tried it with go tip and go 1.0.

T(go tip) / T(go 1.0.3) = 0.8

Thus one might expect go to take third place after clang and gcc. But keep in mind that e.g. java isn't the newest version either...

Just tried it myself with the C version and with 1.0.3,

  C:  ./a.out < sudoku.txt      0.07s user 0.00s system 94% cpu 0.077 total
  Go: ./sudoku_v1 < sudoku.txt  0.06s user 0.01s system 88% cpu 0.079 total

Which seems a bit interesting...
