we have 2 windows VMs (windows server 2008r2), that show some
we traced it down to calls to QueryPerformanceCounter() to get
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?
