So, situation looks pretty *terrible* on baremetal. Well, something to
investigate, I guess.

In VMs, on the other hand, things don't look too bad. Although, it's a
bit weird that the benchmark seems to be sensitive to HT when run on
baremetal, but not so much when run in VMs. Among the various core
scheduling implementations/patches, plain v3 seems to have issues with
this workload, while Tim's and vruntime are better.

It is confirmed that, in virtualization scenario, under
overcommittment, core scheduling is more effective than disabling
HyperThreading, at least either with Tim's or with vruntime patches.

Overhead wise, it is an hard call. Numbers vary a lot, and I think each
group of measurements needs to be looked at carefully to come up with a
sensible analysis.

Overhead is there, that's for sure, in the baremetal case. Also, it
looks more severe when HT is disabled (e.g., comapre v-BM-noHT with BM-
noHT).

In virt cases, it's really an hard call. E.g., when a VM with 4 vCPUs
is used, core scheduling seems to be able to make the system
significantly faster! :-O
