Systems, methods, and computer-readable media for reducing latency in TCP connections that utilize loss insensitive congestion control mechanisms. In some examples, packet arrival times for one or more TCP packets of a TCP connection are analyzed and based on the analysis, it is determined whether the packet arrival times are constantly spaced over a period of time. Whether a TCP control mechanism for the TCP connection is loss insensitive is identified based on whether the packet arrival times are constantly spaced over time. If it is determined that the TCP control mechanism is loss insensitive, then a total number of acknowledgement packets transmitted during the TCP connection and associated with transmission of the one or more TCP packets in the TCP connection is reduced.
