Hi Paolo, I am very surprised about the live migration performance result when I use your ' memeqzero4_paolo' instead of these SSE2 Intrinsics to check the zero pages. The total live migration time increased about 8%! Not decreased. Although in the unit test your ' memeqzero4_paolo' has better performance, any idea? Liang
