9099	4 cores Guest Cpu saturation while host cpu load around 37%	Gianks		"While the guest operating system reports 4 * 100% CPU usage in task manager, top over my linux host reports VirtualBox using just 150% of my total processor. looking at single cores no one reaches 100%.

I've read about poor multiprocessor guests performances in the manual but i don't understand if this behavior may be included or has to be considered ""normal"".
