Question

我用Java编写了一个客户端代码，用于将文件上传到我们的服务器之一。在Ubuntu机器中，客户端能够以5 MB / s的速率将文件上载到服务器。但是在Windows 7中，上传仅以60 kB / s的速率发生（禁用防病毒和防火墙）。

代码段如下：

.......................

URL server = new URL(url);

HttpURLConnection connection = (HttpURLConnection)server.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setInstanceFollowRedirects(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("content-length",fsize);
connection.setRequestProperty("charset", "UTF-8");
connection.setRequestProperty("file-name", file.getName());
connection.setFixedLengthStreamingMode((int)file.length());
connection.setReadTimeout(30000);

if (file.exists()) {
    connection.connect();

    OutputStream out = connection.getOutputStream();
    BufferedInputStream in = new BufferedInputStream(new FileInputStream(path));
    byte []buf = new byte[256*1024];
    int length=0;
    try {
    while ((length=in.read(buf))!=-1) {
        out.write(buf, 0,length);
    }
    out.flush();
}
..............

请告诉我是否需要添加任何HTTP标头（或）我应该对代码进行任何更改。

的问候， kit_kings

Windows 7中的上传速度为60 kB / s
