Hello
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
Regards
