I suspect you may need the following patch to improve your 4.1.2
performance:

The cache flush on every C2 transition is very expensive and causes
a large slow down.
4.1.3-rc3 already includes that patch so it would be worth testing
that version.
MA Young, could this be back-ported in the F17 and F16. I belive
Micahel Petullo setup a bug for that?
I don't recall I seeing a bug for this but the patch is in
xen-4.1.2-25.fc18 and xen-4.1.2-25.fc17 (which is building now).
