Interesting. Could this be mitigated at all with QUIC hardware? It seems like if the tradeoffs are this bad at scale Google wouldn't be pushing QUIC.

  It can be mitigated, and companies are working on it. However, there is no NIC offering hardware QUIC protocol offload that I'm currently aware of. Part of what makes it challenging is one of the features of QUIC: That the protocol headers are themselves encrypted.

    But do the headers have much to do with power efficiency? Seems like that would mostly hinge on encryption and state machine efficiency.

      They have to do with the viability of offloading. You can't give the NIC an encrypted stream and have it handle the protocol stuff if it needs to put things inside the encryption to do so.

    The Intel 700 and 800 series NICs have a DDP for QUIC.
