I have Windows 7 host machine with 4GB ram and Core-i7 Processor. I have a Virtual Box VM (running linux) and 1.6 GB memory is assigned to it. The problem is when I close my VM, my host machine becomes very slow. All those processes which were minimized in the taskbar take too much time to become active again.
I think all those processes are swapped to disk while VM was running and it takes time to get them back. but it is too annoying because the system takes about half an hour to get back to normal state.
Is my hypothesis right or there is some other problem? and If I am right then what should be the solution for this.
My hard drive is 620 GB SATA Samsung HM641JI having single partition. It is a single drive maybe that is the problem? can defragmentation help?
