Does virtual machines affect performance?
When several virtual machines are running on the same host, performance may be hindered if the computer it’s running on lacks sufficient power.
Your virtual machine still uses the resources of your host machine.
The more powerful the host computer, the more quickly the virtual machine will run..
Why do virtual machines run slow?
If free memory falls below the minimum necessary value (specific to each host computer’s configuration), the host operating system will continually free up memory by swapping to disk to maintain that amount of free memory; this in turn causes the virtual machine to run slowly as well.
