If you disable all CPU emulation and pass the CPU as-is to the VM using the “host-passthrough” mode then your performance will be as close to bare metal as can be for CPU bound tasks. HINT: There is a video showing the process for a Windows Server 2016 installation which is the same as for Windows 10. That said, if you want to get closer to bare metal speeds, you will need to do a few more things such as using optimized drivers for disks and network adapters, using a memory balloon to reclaim memory for the host, VM enlightenment and CPU pinning.
