Question

我不知道在Title中写了什么，对不起！
我有这个脚本，我从ZwQueryDirectoryFile获取下载数据并带有标题：

<?php
// hide notices
@ini_set('error_reporting', E_ALL & ~ E_NOTICE);

//- turn off compression on the server
@apache_setenv('no-gzip', 1);
@ini_set('zlib.output_compression', 'Off');

//Getting upload center and append file name

$file_path = $_SERVER['DOCUMENT_ROOT'] . $dir_path;
$file_name = pathinfo($file_path)['basename'];

// allow a file to be streamed instead of sent as an attachment
$is_attachment = isset($_REQUEST['stream']) ? false : true;

// make sure the file exists
if (is_file($file_path))
{
    $file_size  = filesize($file_path);

此脚本在我测试的Linux服务器中运行良好。我可以恢复下载并在IDM中获得 8连接以及所有内容，但IIS我只是 1个连接每次停顿后，我都要等几秒钟，否则我会Server Closed Connection 我在两台服务器上都安装了php版本，并使用Windows Server 2012和IIS 8完成了教程中的所有配置。
那么这里的问题是什么？
（虽然我不得不说从Server 2012直接下载没有任何问题且效果很好。）
修改我也使用Nginx在Windows服务器上测试脚本，但与IIS相同，它无法正常工作。

（PHP）Apache中的脚本运行良好，但不适用于IIS
