Even though you're only using US-IIIi CPUs, the same issue applies here.
You're running a single threaded workload on 4 CPUs which are better at
multithreaded workloads (US-IIIi) and comparing it to running a single
threaded workload on a CPU optimized for a single threaded workload (Intel).
At least that's what you appear to be doing (to me) from looking at your
snippet and reading your description of the problem.
That's comparing apples to loafers.
