Vitualbox: slow down when using more than 1 processor (AMD)

Haiku slows down when assigning more than 1 processor to the virtual machine. I tested with an AMD Phenom II processor assigning from 2 to 4 processor, getting the same slow down. I don't have an Intel processor to test on.
When running with only 1 processor everything is ok. Everything returns to normal speed when I reduce the number of processors assigned to the virtual machine or when I disable the extra processors in the deskbar.
I also tested running Haiku in the bare hardware and using the 4 cores of the cpu does not trigger the slow down, only when using Virtualbox.
Versions used: Virtualbox 4.2.12 on Windows 8. Haiku R1/Alpha4.1
