I'm using VirtualBox 3 on my Ubuntu 9.04 desktop, and I've got a VM with Windows XP sp3 mapping my ~/Documents folder as a shared folder. The virtualised Windows is mapping My Documents to the shared folder directly (//vboxsvr/Documents).
The problem is that every time that I'm interacting with the shared folder (i.e.: access, list files, etc.) it takes several seconds to do so.
Is there a way to speed this up?
