4586	Still very slow SMP operation on 3.0.2 with Linux 64-bit host and Windows XP 32-bit guest	Matti Rintala		"I upgraded from 2.x.x to 3.0.2. My host is Opensuse 11.1 64-bit, and I'm running Windows XP 32-bit guest on a Intel Core 2 processor.

Running my old virtual machine (from 2.x.x) works as before, but utilises naturally only 1 CPU. When I create a new virtual machine with 2 CPUs, it is unbearably slow. Installing Windows XP and its updates took hours, and running the virtual machine after it is equally slow. Later editing virtual machine settings to allow only 1 CPU changes nothing in this respect, the virtual machine is still slow.

Host CPU utilisation drops when the guest is idle, but when the guest is actually doing something, both CPU cores show almost 100 % most of the time."	defect	closed	other	VirtualBox 3.0.2	duplicate	SMP		Windows	Linux
