ABSTRACT:
Systems and media for detecting outbound Nagling on a TCP network connection are disclosed. Embodiments may include creating by a sender computer one or more segments to be transmitted to a receiver computer and determining by the sender computer whether any of the one or more segments to be transmitted are small segments and determining whether a previously transmitted small segment is unacknowledged by the receiver computer. If the previously transmitted small segment is unacknowledged by the receiver computer and at least one of the segments to be transmitted is a small segment, embodiments may also include detecting by the sender computer a Nagling condition on the network connection. Further embodiments may include modifying a Nagle algorithm configuration of the network connection in response to the detected Nagling condition by turning off the Nagle algorithm or reducing a delayed acknowledgement timer for the network connection.
