I did the m4 build test on a
cpu0: "Intel(R) Xeon(R) W-2223 CPU @ 3.60GHz"                   

PVH
       47.39 real        31.13 user        13.48 sys
       47.19 real        31.27 user        13.54 sys
       47.26 real        31.23 user        13.65 sys
       47.65 real        32.26 user        13.01 sys

PVHVM
       47.30 real        31.13 user        13.36 sys
       47.07 real        31.30 user        13.39 sys
       47.55 real        31.80 user        13.37 sys
       47.13 real        31.89 user        12.89 sys

(no bare metal test here, it's a production machine).
I'd say the time differences are actually in the noise margin - especially
as the host is not idle.
