I have been searching for documentation on how to properly enable the HPET on a Hyper-V. I haven't been able to find anything specifying if it works or not, and if it does work, how to properly enable it. From our initial tests, it doesn't seem to be consistent
with either the machines timer or the HPET.
We are deploying Lync and UCMA based applications and have noticed a significant performance difference between machines with HPET enable and HPET disabled in terms of their ability to handle capacity. We would like to be able to virtualize these machines, but the HPET is currently our limiting factor.
Can anyone point me in the right direction to find an answer?
