            static int maxTimes = 10000000;

            static void TestAsync()
            {
                Stopwatch sw = new Stopwatch();
                sw.Start();
                Task t = Task.Run(() =>
                {
                    for (int i = 0; i < maxTimes; i++)
                    {

                t.Wait();
                sw.Stop();
                string cost = $"Async cost {sw.ElapsedMilliseconds} milliseconds";
                LogCost(cost);
            }
    
            static void TestSync()
            {
                Stopwatch sw = new Stopwatch();
                sw.Start();
                DoWork();
                sw.Stop();
                string cost = $"Sync cost {sw.ElapsedMilliseconds} milliseconds";
                LogCost(cost);
            }
    
            static void DoWork()
            {
                for(int i=0;i<maxTimes;i++)
                {
                    string msg = $"{i}i,Guid:{Guid.NewGuid().ToString()}";
                    LogMsgSync(msg);
                }
            }
    
            static void LogMsgSync(string msg)
            {
                Syncsw.WriteLine(msg);
            }
    
            static void LogMsgASync(string msg)
            {
                Asyncsw.WriteLine(msg);
            }
    
            static void LogCost(string cost)
            {
                File.AppendAllText("time.txt", $"Time:{DateTime.Now.ToString("yyyyMMddHHmmssffff")} {cost}{Environment.NewLine}");
            }

    The time cost as below.

    Time:202006151201519630 Sync cost 9596 milliseconds
    Time:202006151202006961 Async cost 8726 milliseconds

    The fact has illustrated that the async has speed advantages
