perhaps it would be a good start to reimplement newbytes(n) using
memalign(16,n) instead of malloc(n).

Fix the loop sizes to a literal so the compiler has some clue as to how the loop is structured. The compiler will not figure out passing a runtime parameter in for the loop size.

It should be noted that most 'benchmarks' for the auto-vector features are heavily rigged and not like anything used in the average application. See further http://www.spec.org/
