The representative embodiments discussed in the present disclosure relate to techniques with which data packet loss, such as Transmission Control Protocol (TCP) packet loss, may be detected. More specifically, in some embodiments, by detecting a TCP packet with an enabled selective acknowledgement (SACK) signal, the loss (e.g., drop) of an additional TCP packet may be determined. Moreover, using information included in the detected TCP packet, an operational efficiency of a cloud computing system and/or a component of the cloud computing system may be determined.
