Hash vTLB is intended to address SMP scalability for large system. Kernel build on dom0 loses about 2% performance, While dom0 can support non-contiguous memory, and can address Hugetlb issue. Those incur performance degradation. Kernel build on domU gains about 1% performance. Signed-off-by: Anthony Xu <anthony.xu@xxxxxxxxx> Thanks, -Anthony
