We have tried the performance improvements that we have heard of but
still have some slow screen updates. We are running the VNC server built
into Red Hat 5.4 qemu-kvm with over 1+ MBit networks. The "machines"
being connected to are virtual machines running under KVM.
1. Windows: Moving a window around over a clear desktop. The speed
option has been set in the Advanced tab.
2. Linux: Some Linux preboot that starts before Windows boots. Here
there are double mouse cursors.
Any help will be appreciated.
