Windows 10 Virtual Machine Benchmarks

Benchmarking Performance of a Virtual Machine

I have run  a number of benchmarks to document the performance of Windows 10 running as a virtual machine on Linux, in the hope other PC users will dive into the fascinating world of virtualization.

Benchmarks are helpful in comparing one system with another, and one configuration with another. I use them for optimizing my Windows 10 performance and for making sure that updates/upgrades haven’t produced unwanted side effects.

Obviously the most important benchmark is the user experience. If you feel that something is wrong, sluggish, etc., then all the benchmarks in the world can’t help achieve a different experience.

Warning: If you benchmark, don’t overdo it! Particularly disk benchmarks have the unwanted side effect that they actually reduce the lifetime of an SSD.

SteamVR Performance Test

My latest benchmark is the SteamVR Performance Test. This benchmarks runs on a Windows 10 (1803) VM and tests if the machine is ready for VR (virtual reality).

The next thing to do is to carry my PC to the next room and connect it to an actual HTC Vive. If time permits, I’ll do that.

Passmark 8 Benchmark

I’m using Passmark 8 instead of the latest version 9 since that is the version I bought. Passmark has a nice breakdown of different benchmarks, including 2D graphics performance tests, which are important to what I do under Windows. The benchmarks run on a Windows 10 (1803) VM, and I have included the benchmarks of a Windows 10 (1803) bare metal installation for comparison.

Legend:

  • Red graph – Windows 10 (1803) on bare metal
  • Blue graph – Windows 10 (1803) VM with Spectre protection enabled
  • Yellow graph – Windows 10 (1803) VM with Spectre protection disabled

Here is the Passmark Rating for my Windows 10 Virtual Machine:

Windows VM regains 2D performance
Windows 10 VM regains full performance when Spectre protection is disabled
