I've got an end-user with an issue running VirtualBox 3.0.12 on OS X 10.6.2, Windows 7 32-bit Guest. The performance when dealing with Shared Folders is appalling. I've seen a lot threads that pretty much say the same thing, so I'm going to try and give up as much information as possible. I'd like to assume this is due to the newness factor of Windows 7.
1536MB RAM 2 vCPUs VT-x/AMD-V: Enabled Nested Paging: Enabled ACPI: Enabled Display: 12MB 3D Acceleration: Disabled Hard Disk: SATA Port 0, Normal, 60GB Audio: CoreAudio, ICH AC97 Adapter 1: Intel PRO/1000 MT Desktop
I've tried using the /drivers/etc/hosts file fix that was posted for several Windows XP guests. While this does cut down on the level of waiting and freezing, it's still at a level that's unacceptable for this person's day-to-day work (editing documents, attaching pictures generated in OS X to e-mails in Outlook, presentation devleopment, etc.). I did some tests jockeying settings back and forth with the network adapters, hosts file, etc. 3 times each opening the file, averaged out. I then copied the file from the shared folder onto the Windows desktop and opened it there for a baseline native comparison. Keep in mind this is an 11KB Word Document, as well as the fact that these times do not include the initial Word startup lag. I also rebooted in between adding and removing the hosts fix. Chart is attached.
I've never seen performance this bad in a guest before. Obviously the closest to native performance are the numbers with no Networking enabled, but for an end-user this is not acceptable to have to constantly turn networking on and off to work with files.
