That overhead happens about 30% of the time, so an instance uses about 130% cores average. But there are peaks of 200%. When I run 3 instances on 4 cores, they use all cores most of the time, but you see one idle core sometimes (and it´s not uploading).
When running test beds, I run one instance per core (and disable turn skipping), so all cores are used all of the time.
Running a benchmark restricting each instance to a single core would remove that parallel overhead.
