I'm very impressed with the speed that my VMs run at in VBox comparing it to VMWare, but I still think VMware leaves my host system more responsive while running VM's.
It seems that VMWare uses the host's ram where VBox uses a lot more of the page file when I look at Task Manager. I'm just wondering if the performance of VBox can be improved by altering the usage of the host's resources to be more like VMWare?
