Thanks for pointing this one out.

The original Xen paper  and our repeated research paper 
showed a decent dbench "score" vs. native.
dbench is known to have a high standard deviation...
some KVM results for dbench:
dbench is an interesting test since it is basically an I/O test (Samba test)
I don't know if dbench is the best test to determine if Xen (or other
to be fixed.
