XFCE OK with compositor is ON but still v. slow.

M$ win7 guest w 640Mb,  64 video+2D/3D is almost as fast as the host.

I think this is to do with the graphics but can anyone give us any sort
of comparison of what to expect?


I teach Linux at a Technical college and use openSUSE, running on virtual
machines, on vmware and virtualbox 4.1.x, myself I use openSUSE as host on
all my computers.

I've observed, that when running openSUSE 12.1, in a virtual machine, that
on the first run, when akonadi, all the desktop search engines, and man
pages etc. initialize on first run, the virtual machine runs very very slow,
to the point of being non-responsive. Once everything is done initializing I
shutdown akonadi, desktop search etc...., from that point on vm runs well.

Not sure this is the same issue as yours,  all my host computers are using
Nvidia, however I'm not using the 3d, stuff.

Yes, I think I can say that we are passed all the initial first login stuff
and also we are on XFCE.
e.g. top gives: 1053 root      20   0 71816  26m 6700 S 1053 root      20
0 71816  26m 6700 S  5.3  5.4   0:21.03 Xorg  5.3  5.4   0:21.03 Xorg
 load average: 0.23, 0.34, 0.57
 after the initial login with Xorg in the top three most of the time:
 1053 root      20   0 71816  26m 6700 S  15.3  5.4   0:21.03 Xorg

The strange thing is that it is more responsive with the compositor
selected. Without it the screen redraw (e.g. desktop icons are not redrawn
immediately) is painful. The amount of actual and video memory I give seems
irrelevant.

I don't think the Vbox 3D acceleration is working. How to check?
Thanks,

Have you installed the VirtualBox Extension Pack?
http://download.virtualbox.org/virtualbox/4.1.8/Oracle_VM_VirtualBox_Extension_Pack-4.1.8-75467.vbox-extpack

Have you installed the Guest Additions:

The Guest Additions make a HUGE difference in the graphics performance
of your guest machines.
