Not really - since the bare metal provisioning tends only to be large, expensive instance types. The benefit of secure OS-level virtualisation is that you can co-locate the smaller workloads of multiple tenants on the same bare metal, while not incurring the overhead of hardware virtualisation.

When you compared the utility of JCP "tiny" instance (1 CPU worth of shares, 256MB of RAM) to a t2.micro or similar instance in AWS, the difference was astounding. Part of this is the CPU credit mechanism on T2 instances, but I'd wager that a good part of it was being in OS-level virtualisation.
