    NUMA, SMT and cache: when hardware topology starts to matter

    Two workloads can get the same CPU time and do different amounts of work. This is where the CPU abstraction ends and the physics of the machine begins.

    CPU time and CPU placement are two different mechanisms. A limit says how much you may consume; affinity and cpuset say where a task may execute.
