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?

Thanks

What capacity and speed of disk are you using? – tombull89 Oct 12 '12 at 10:51
Your hypothesis cannot be right. It couldn't possibly take half an hour to swap 4GB of stuff or less. – David Schwartz Oct 12 '12 at 11:01
I have 620 GB Samsung HM641JI having single partition . According to specs its media transfer rate (max) is 138 Mbps. – Kanwar Saad Oct 12 '12 at 11:20
@KanwarSaad Mb or MB? – MDMarra Oct 12 '12 at 13:47
Coonsidered putting more memory into it than a tablet has? 4gb is something I run my secretary on these days. VM hosts have a minimum of 16gb - 64gb for production level use. Memory is CHEAP. Just purchasing another 64gb ECC set for about 600 USD or so. – TomTom Oct 12 '12 at 13:47

It could be an IO problem as you already stated. I don't know what harddisc you are using on the host machine. Are you shutting down the VM or suspending tho? Because with suspend I guess it will write the memory data to disk too.

whether i suspend or not ... there is same result in either case. I have 620 GB Samsung HM641JI drive with no partitions. – Kanwar Saad Oct 12 '12 at 11:18
its a single huge drive maybe thats the problem ... can disk defragmentation help? – Kanwar Saad Oct 12 '12 at 11:27
