Retransmission times become very long if there is packet loss near the beginning of the connection.
Uninitialized ack_delay variable could be any value and cause RTT measurements to be unusually large. That could cause retransmission times to be very long if there is packet loss near the beginning of the connection.
-- Basic QUIC configuration. -- The first couple of packets in the connection reaches an uninitialized variable path before the connection reaches the ESTABLISHED state.
N/A
Reusing existing ack-delay variable fixes the issue.
