recompile QEMU for raspberry 2 to use 4 cores

Hello,
I've installed Windows XP on raspberry 2 using QEMU.

The emulation is very slow, but qemu use only one core of raspberry 2, so the overall cpu level is about 25%

How let QEMU use 100% ?
I thinks that I need to recompile QEMU... what option I need to use?

Thanks in advance
Giorgio
