MS Windows desktop OSes are not the best platforms to run multiple VMs on. Also, overcommitting CPUs has a bad influence on performance, especially if the host wants to use all cores as well. I run VMs regularly and am not surprised at this. I always use Linux as the host as the scheduler there works better for this kind of usage. -- Joost -- Sent from my Android device with K-9 Mail.
