An interesting and mysterious fact is that measurements are very stable for FP and VMX tests, but vary a lot for INT tests. This is possibly the same weird problem I had measuring some other code (see Head Scratching). I have still no clue, what the reason could be, but I am sure that knowing the reason would be enlightening.
