Raptor Lake efficiency cores in Linix with Docker? - eviltoast

Hey all,

Anyone familiar with the state of Raptor Lake performance + efficiency cores in Linux? I’m specifically curious about how the kernel balances things when running multiple containers (without pinned CPUs)

Thanks!

    A Docker container is a security framework. The process running “inside” the container is just a Linux process like any other.

    So, as I understand it, the performance will be identical to a process that is running “outside” a container, subject to the overhead associated with any security restrictions.

      Yes, this is the case, I’m more wondering about kernel support for CPU assignment as it relates to those processes.

        I think that what you’re looking for is “CPU affinity”, but that is not something I know anything about.

        In the 40+ years I’ve been playing with computers, I’ve always let the OS worry about where and when to run a process and only rarely do I renice a process that needs to run, but not at the expense of everything else.

          Agreed, just want to make sure the kernel can handle resourcing for two different types of cores. I know there was a time (recent) where it couldn’t. Others have said 6.x is the key.
