The smaller cores are not really much different from having other applications / kernel / device drivers running concurrently with your workload. Bad design: see N cores, split work into N partitions, start N threads, each thread processes one partition. Good design: see N cores, start ~N threads, each thread takes 1/M of work at a time, M>>N.
