Description Emin Kokalari 2017-03-19 14:14:30 UTC
When pinging for example 8.8.8.8 from mono System.Net.NetworkInformation reply time is very higher than pinging from Lava.Lang.Process ex. ping -c 10 8.8.8.8

    PingReply Reply = await pingo.SendPingAsync(text_ip.Text, 4000);
            Toast.MakeText(Activity, Reply.Status.ToString(), ToastLength.Long).Show();
            switch (Reply.Status)
            {
                case IPStatus.Success:

                    Toast.MakeText(Activity, Reply.Status.RoundTripTime().ToString(), ToastLength.Long).Show();
                    break;
 

if here is estimate ex. 100 ms


in this other example it shows 40 ms lower ex. 60 ms.

    Process ipProcess = runtime.exec("ping -c 1 8.8.8.8");
        int exitValue = ipProcess.waitFor();
        ipProcess.destroy();

        if(exitValue == 0)
        {
            // Success
        } 
           else 
        { 
             // Failure
        }

Why is this happening ?
