VM working very slow


I have got problem with one VM (Windows 2008 R2), it has 4 GB RAM and due to JVM based application it works very very slow. How do I determine whether I should upgrade RAM or I should reserve resource on VM.

There should be no need to reserve resources for the VM, unless your HOST environment, is short of RAM, and RAM is being stolen from this VM.

You would only reserve or ring fence RAM resources, to guarantee memory for a VM, if it's being stolen by other VMs.

So overall, how much memory is in the host, how many VMs do you have, how much memory is free.

and how much is left for the host.
