It's not about traffic identification at all, but rather a hashing algorithm that is deliberately resistant to parallelization and GPU/ASIC acceleration, which shrinks the gap in solving speed between the fastest systems (i.e. datacenter-class compute resources) and typical systems (e.g. the CPU in your smartphone or laptop).
