Only if you have more containers than cores.

That depends on what your scheduler does. Having one virtual core doesn't necessarily mean you always get the same physical core.

Also you said "a lot of workloads" so yes probably more containers than cores.

Most of my pods have a CPU request >= 1 so more containers than cores is rare. But obviously that really depends on your workload(s).

I don't think the scheduler picking a different core matters much unless your workload is super cache sensitive. My point is more about access to single threaded performance. If you have a single threaded workload (ex: an ffmpeg audio encode) and you want it to be able to access as many cycles from a single core as possible, it isn't always as simple as request: 1
