27 MS Windows desktop OSes are not the best platforms to run multiple VMs on.
29 Also, overcommitting CPUs has a bad influence on performance, especially if the host wants to use all cores as well.
31 I run VMs regularly and am not surprised at this.
33 I always use Linux as the host as the scheduler there works better for this kind of usage.
