Windows 10 poor performance compared to Windows 7 (page fault handling is not scalable, severe lock contention when no of threads > 16)
问题 We set up two identical HP Z840 Workstations with the following specs 2 x Xeon E5-2690 v4 @ 2.60GHz (Turbo Boost ON, HT OFF, total 28 logical CPUs) 32GB DDR4 2400 Memory, Quad-channel and installed Windows 7 SP1 (x64) and Windows 10 Creators Update (x64) on each. Then we ran a small memory benchmark (code below, built with VS2015 Update 3, 64-bit architecture) which performs memory allocation-fill-free simultaneously from multiple threads. #include <Windows.h> #include <vector> #include <ppl
