Ekkas,are you here? There is a question......

I have tried PCC and NTH these days,my experience is PCC less than NTH in bandwidth utilization,but I feel that NTH is evidently longer latency than PCC,why NTH has longer latency than PCC that much? Is that normal or just I make some mistake in somewhere?

I appeal to ekkas since he has many years' experiences in NTH, other professionals' answer will be please welcome. Thanks

What is your configuration? Where is the problem to use PCC?
