Yes it goes faster.

The reason is fairly simple: run-emulator.sh couldn't know if the host
is KVM capable.
Instead qemu knows it indeed on my Ubuntu Natty system it checks that
condition automatically:

alessio at granny:~$ qemu
open /dev/kvm: No such file or directory
Could not initialize KVM, will disable KVM support
qemu: pci_add_option_rom: failed to find romfile "pxe-rtl8139.bin"
