The best practice is to always provision CPU and memory resources sparingly, and then increase them as you see the application's performance. This allows the VM to use allocated resources efficiently, which in turn makes all the VMs run efficiently in the node. By over-provisioning CPU and memory for all VMs in the node, we degrade node performance, because all VMs will be fighting to have more CPU time.
