  • Data Scenario:

    Network Connection: Fibre 300 Mbits (U/D)

    Browser: Mozilla Firefox 98 (x64) -> no tracking add-ons nor FF tracking enabled

    Site tested -> Direct download of Ubuntu ISO:


    Kaspersky Product K. Plus

    • Anti-Banner and Private Browsing modules disabled
    • Network Settings -> Limit Traffic on metered connection: disabled + Monitored Ports: All network ports

    I took traces for about 2 or 3 minutes until the direct download got established:

    • With Kaspersky enabled: maximum speed -> 11 MBytes/seg
    • With Kaspersky disabled (Exit): maximum speed -> 24 MBytes/seg

    If I use a 3rd party downloader tool even with Kaspersky enabled -> Free Download Manager, to download the same file, I get the full speed -> more than 30 MBytes/seg
