I suspect you'll see several instances of flat parts on the Windows graph that precede Slow Start events, but few, if any in the Linux graph because Linux's fancier congestion avoidance algorithm managed to avoid. This command will check for updates and upgrade any outdated packages on your Ubuntu system. A Wireshark TCP Time Sequence graph of each test would probably be enlightening, since such events are pretty easy to see that way. First, open a terminal window, and run the command below to update your package repositories.

Filtering Packets with Filter String and Filter Expressions.Then compare the content of the capture files with what you expected to get from the packet generator. You need more than a few tests with identical test parameters, to filter out CPU usage peaks or IO peaks that might have an influence on the test result. Then you capture 10 times (or more) with Linux and 10 times with windows. Capturing Packets using the Wireshark GUI If you want to compare results, you need a packet generator that generates the same data every time you test.
