What at the VMs doing?  Are they entirely idle?  Are they doing light 
work, mostly reading from disks?  If they're not generating disk IO, 
then that's not related.  However, during a recent set of benchmarks, I 
found that disk reads were slower under 7.3 than under 7.2.  That might 
be specific to the system I tested, or it might be related to the change 
you're seeing.
