> The long and short of it is that if you’re building a HPC application, or are sensitive to throughput and latency on your cutting-edge/high-traffic system design, then you need to manually pin your workloads for optimal performance.

Last time I was architect of a network chip, 21 years ago, our library did that for the user. For workloads that use threads that consume entire cores, it's a solved problem.

I'd guess that the workload you had in mind doesn't have that property.
