hi, we have 2 windows VMs (windows server 2008r2), that show some performance problems.
we traced it down to calls to QueryPerformanceCounter() to get timing information. we tried enaling hv_relaxed,hv_spinlocks, hv_apic and hv_time in an test, however that did not really help we still have significant slowdown for every call to the performance counters (for some artifical tests we got to up 12 times the runtime compared to relativly similar physical hardware). does anybody here now about any solution to this problem? regards, albert dengg
