Thread: RWIN Numbers

    RWIN Numbers

    When I run the TCP/IP Analyzer the RWIN shows to be 64240 with auto tuning disabled and 655420 or something like that with auto tuning enabled.

    My question is, where does the Analyzer get these numbers? Running Windows 7 Pro.

    When you connect to the Analyzer server, it dissects the TCP/IP packet headers, and shows what your computer advertises to our server. Windows 7 and newer OSes can modify the RWIN value on the fly when auto-tuning is enabled based on your connection speed and its quality at the moment, so each packet may advertise a different RWIN number.

    I hope this helps.
