中间件 - 性能问题

Question

我正在为我的客户开发一个中间件，发现在执行该过程时会有一些延迟。

我们目前正在研究从架构设计到编码的问题的确切原因。

下面是我们调用的脚本的一部分，只是想知道代码本身是否已经过优化和正确编写？

以下代码中存在无错误，只是想知道是否存在性能或编码问题。 TKS

public string getResponse(System.Type type, Object input, string taskName, string method)
{
    string response = string.Empty;

    try
    {
        DataContractJsonSerializer ser = new DataContractJsonSerializer(type);
        MemoryStream mem = new MemoryStream();
        ser.WriteObject(mem, input);
        string data = Encoding.UTF8.GetString(mem.ToArray(), 0, (int)mem.Length);

        using (WebClient webClient = new WebClient())
        {
            webClient.Headers["Content-type"] = "application/json";
            webClient.Encoding = Encoding.UTF8;

            logger.Info("Sending [" + method + "] request to API[" + string.Format(Configuration.getTargetURI(), taskName) + "]");

            response = webClient.UploadString(string.Format(Configuration.getTargetURI(), taskName), method, data);

            logger.Info("Response of API[" + string.Format(Configuration.getTargetURI(), taskName) + "] successfully retrieved");
            logger.Debug("Response: " + response);
        }
    }
    catch (Exception ex)
    {
        logger.Info("Failed to invoke [" + method + "] request to API[" + string.Format(Configuration.getTargetURI(), taskName) + "], Error: " + ex.Message);
        logger.Error(ex.Message + ex.StackTrace);

        throw ex;
    }

    return response;
}

public string getResponseNoInput(string taskName, string method)
{
    string response = string.Empty;

    try
    {
        WebRequest req = WebRequest.Create(String.Format(Configuration.getTargetURI(), taskName));
        req.Method = method;
        req.ContentType = "application/json; charset=utf-8";

        logger.Info("Sending [" + method + "] request to API[" + string.Format(Configuration.getTargetURI(), taskName) + "]");

        HttpWebResponse resp = req.GetResponse() as HttpWebResponse;
        using (StreamReader sr = new StreamReader(resp.GetResponseStream()))
        {
            response = sr.ReadToEnd();
        }

        throw ex;
