I have used the guest via VNC and RDP and received the same performance. The XP guest does not appear to have high i/owait. I have tried both apic=0 and apic=1. And my host OS is all up to date. Xen 3.4.2 may be an option, but I think I am going to pursue VMWare ESXi at this point. I appreciate your help and all of your suggestions. Thanks, Ryan
