FreeBSD jails it is then.

  I don't know anything about Solaris Zones, but I'm guessing that the FreeBSD jails wouldn't help with the problem in the article. It's still the same kernel running in the jail, so the fadvise calls are going to bottleneck in the same place.

    Why would an entirely different piece of software have the same performance bottlenecks?

      Because the problem isn’t that there is one bug in a specific implementation, it’s that the whole model is fundamentally prone to this type of problem. cgroups, Jails, and Zones all suffer from having to cover an immense surface area. Contrast with VMs, which only require managing a few, significantly simpler interfaces. There are definitely differences in quality, but they all use a similar approach.

        OP says that fadvise is going to bottleneck in the same places on BSD that it does under Linux, with no supporting evidence. I agree that containers in general are a tough problem.
