Well. We don't have shm for vnc. And I think the reason simply is that
it feels fast enougth even without shm. Spice tries to reduce the
network bandwith needed with image caching, so with spice the gains by
using shm should be even smaller than with vnc.
I'm not aware of anyone trying + benchmark it, but I don't expect major
gains.
cheers,
Gerd
