Isn't the performance penalty only if you compare current Qemu with and

Nope, qemu-fast uses a patched Linux kernel (yes, the guest can
*only* be Linux) to run Linux at very-close-to-native speed
with very little translation in a different address space.

If you only intend to run Linux VMs and don't have a problem
patching the kernel sources this is a very viable approach to
get something which is not possible anymore *without* kqemu
which is more flexible but does only run on 32bit kernels ATM.
