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?

I have the exact same problem with an XP Host and both an Ubuntu guest and XP guest. Must be a VirtualBox thing (versus an O/S thing). I'd be interested in seeing a solution. – Michael Todd Jul 21 '09 at 22:41
I think it is only slow in listing. Writing and reading are not slow. – bert Nov 18 '09 at 20:35

It seems to be an issue with name resolution. That happens on Windows machines while it tries to use the virtual network adapter to resolve the name. I have resolved this issue on a Windows host, but not on an Ubuntu host.

I found this site that has some suggestions.

Already saw the linked-to site but it did not help me... editing \etc\hosts has no effect on speed, and anyway my share is already mounted as a drive letter, but access to it is still far slower than local disk. 4.1.2 guest additions. – Jesse Glick May 8 at 15:34
