如何在c＃中更快地执行http post请求？

Question

我在c＃中的应用程序出现问题，我每隔20毫秒从互联网上接收数据，我需要处理这些数据并使用已处理的数据发出http post请求，但是请求需要很多比从互联网上接收数据更长，这是我的代码：

//data comes from internet every 20 milliseconds
public static async Task CalculateHp(string data)
    {          
        var datos = JsonConvert.DeserializeObject<DataModel>(data);

        datos.hp = datos.rpm * datos.torque / 5252;
        datos.now = DateTime.Now;

        var jsonArray = new JArray();
        var jsonStringObject = JsonConvert.SerializeObject(datos);
        jsonArray.Add(JObject.Parse(jsonStringObject));
        var jsonStringArray = jsonArray.ToString();

        var sw = new Stopwatch();
        sw.Start();        
        using (var client = new HttpClient())
        {
            var response = await client.PostAsync("https://url", new StringContent(jsonStringArray, Encoding.UTF8, "application/json"));
        }
        long elapsedMilliseconds = sw.ElapsedMilliseconds;

        //the value of elapsedMillisecons is approximately 500 milliseconds
        Console.WriteLine(elapsedMilliseconds);
    }

有人能给我任何建议或例子吗？
