I don't have a reference, but I'd not be surprised to see on
virtual
machines for this to be even stronger; each invlpg would be a
hypercall, compared to only one for the total flush.
I agree that overhead could be more in virtual machines. Questions
is that does VMs
are designed with evaluation of performance issues at
micro-architetural level. Is this the best design for virtual
machines or Linux ?
I don't see many numbers or published paper to make a claim.

Vineet
