Do you find a lot of disc activity?  I did, but the work around is to
start QEMU with these options (assuming you're using the latest QEMU
from git):

qemu -drive
file=debian-hurd-03102010-qemu.img,index=0,media=disk,cache=unsafe -boot
c -enable-kvm -net nic,model=rtl8139 -net user

After that I found hurd works very fast.
What accelerates your hurd is most probably the use of -enable-kvm, as
that enables native virtualisation support of your CPU. cache=unsafe can
probably help too.
You would think that, but I have found that just enabling KVM makes Hurd disc bound under QEMU, hence the need for the other options as well.
