所以我最近一直在做一个广播控制服务器，但是我在读台词的时候遇到了一些问题。当连接进来时，我正在创建一个新线程，这就是处理连接的地方。所有数据都在被调用的url中提供。例如： /controllerupdate/?_=1597968275949 或者 /api/ . 它们根据url从混合器返回不同的内容。其他所有内容的处理都是最小的（平均<50ms）。
然而 String line = br.readLine() 通话时间最长为700毫秒，这是广播时最长的通话时间。
下面是代码块：

@Override
    public void run() {
        String path = "";
        try {
            //BufferedReader br = new BufferedReader(new InputStreamReader(this.is));
            BufferedReader in = new BufferedReader(new InputStreamReader(this.s.getInputStream()));

            long timeIn = System.currentTimeMillis();
            //String request = br.readLine(); // Now you get GET index.html HTTP/1.1
            String line;

            line = in.readLine();

            long t = (System.currentTimeMillis() - timeIn);

            String[] requestParam = line.split(" ");
            path = requestParam[1];

            if(t > 50) {
                System.out.println("T1: " + path + " :: " + t);
            }

            //Rest of the processing code is here
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

此代码打印出以下内容：

连接的程序是c程序：
以下是执行请求的函数及其调用方式：

private async Task<String[]> doGetRequestWithError(String url)
        {
            if (!url.StartsWith("http"))
            {
                url = "http://" + url;
            }

            //Console.WriteLine(url);

            try
            {
                HttpClient httpClient = new HttpClient();
                HttpResponseMessage result = await httpClient.GetAsync(url).ConfigureAwait(false);

                String error = result.StatusCode.ToString();

                String content = await result.Content.ReadAsStringAsync();

                return new String[] { content, error };

            }
            catch (Exception e)
            {
                Console.WriteLine(e.StackTrace);
                Console.WriteLine("ERROR: " + url);
            }

            return new string[] { "", "" };
        }

呼叫人：

Task<String[]> tsk = this.doGetRequestWithError(this.server + "/mixer?id=" + this.id + "&function=next");

尽管日志中出现的问题是来自ajax调用：

var xhttp = new XMLHttpRequest();
                xhttp.onreadystatechange = function() {
                    if (this.readyState == 4 && this.status == 200) {
                        var xml = this.responseXML;  

                        var inputs = xml.getElementsByTagName("input");
                        var transitions = xml.getElementsByTagName("transition");
                        var numInputs = inputs.length;
                        var numTransition = Math.min(transitions.length, 4);
                        var names = [];
                        var types = [];
                        var isTitle = [];
                        var transNames = [];

                        inputsTmp = inputs;

                        for(var i = 0; i < numInputs; i++){
                            ...
                        }

                        for(var i = 0; i < numTransition; i++){
                            ...
                        }

                        ...

                        $.getScript("http://" + server + "/controllerupdate/?refresh=1");
                        playbackUpdater();
                        window.setInterval(controllerUpdate, 500); 
                        window.setInterval(playbackUpdater, 1000);
                    }
                };
                xhttp.open("GET", "http://" + server + "/api/", true);
                xhttp.send();

这么说来，我只是想知道我哪里做错了？我以前从没遇到过这样的问题！
提前谢谢！
