QUIC: optimized ACK delay. Previously ACK was not generated if max_ack_delay was not yet expired and the number of unacknowledged ack-eliciting packets was less than two, as allowed by RFC 9000 13.2.1-13.2.2. However this only makes sense to avoid sending ACK-only packets, as explained by the RFC: On the other hand, reducing the frequency of packets that carry only acknowledgments reduces packet transmission and processing cost at both endpoints. Now ACK is delayed only if output frame queue is empty. Otherwise ACK is sent immediately, which significantly improves QUIC performance with certain tests.
