套接字的问题在于它们缓冲数据并在缓冲区填充时或在给定间隔内发送它。有什么办法可以避免它并通过高优先级的套接字发送一些东西，没有任何延迟？在我的情况下，毫秒计数。

TCP_NODELAY是您正在寻找的选项

示例代码：

 FileStream fileStream = System.IO.File.OpenRead(Server.MapPath("/10002_en.flac"));
                MemoryStream memoryStream = new MemoryStream();
                memoryStream.SetLength(fileStream.Length);
                fileStream.Read(memoryStream.GetBuffer(), 0, (int)fileStream.Length);
                byte[] BA_AudioFile = memoryStream.GetBuffer();
                HttpWebRequest _HWR_SpeechToText = null;
                _HWR_SpeechToText = (HttpWebRequest)HttpWebRequest.Create("https://www.google.com/speech-api/v2/recognize?output=json&lang=en-us&key=my-key");
                _HWR_SpeechToText.Credentials = CredentialCache.DefaultCredentials;
                _HWR_SpeechToText.Method = "POST";
                _HWR_SpeechToText.ContentType = "audio/x-flac; rate=44100";
                _HWR_SpeechToText.ContentLength = BA_AudioFile.Length;
                Stream stream = _HWR_SpeechToText.GetRequestStream();
                stream.Write(BA_AudioFile, 0, BA_AudioFile.Length);
                stream.Close();
                HttpWebResponse HWR_Response = (HttpWebResponse)_HWR_SpeechToText.GetResponse();

                StreamReader SR_Response = new StreamReader(HWR_Response.GetResponseStream());
                string responseFromServer = (SR_Response.ReadToEnd());

                String[] jsons = responseFromServer.Split('\n');
