Internet 下载管理器(Internet Download Manager)( IDM ) 是适用于(IDM)Windows计算机的流行免费下载管理器。开发人员声称IDM将您设备的下载速度提高了五倍。这是营销噱头吗？
我们将引导您完成 IDM 的下载过程，并比较不同平台上不同文件的下载速度。这篇文章还介绍了影响 IDM 下载速度的因素以及如何配置应用程序以提高下载性能。
5 倍下载速度提升(Download Speed Increase)：这怎么可能(Possible)？
Internet 下载管理器(Internet Download Manager)使用“动态文件分段”技术来加速您计算机上的文件下载。它将文件分成八段并单独下载。
下载进度区域的白色条代表分段，而蓝色条突出显示每个分段的下载分段进度。IDM用一条粉线分隔每个段。
当IDM成功下载文件段时，它会重新分配连接以帮助其他段。IDM将慢速段减半，并减少从主机服务器请求段所需的时间。IDM（重新）将所有下载的片段组合成一个文件并将其保存在您的计算机上。
总而言之，IDM向同一台服务器发出八个不同的请求以下载文件的八个片段。八个(Eight)头比一个更好（更快），对吧？
将 IDM 的下载分段技术想象成派 8 名商店员工从卡车上挑选 32 盒牛奶。他们每个人可以携带四个箱子，并且比将任务分配给一名员工更快地完成工作。
IDM使用类似的方法。它向服务器发送八个（或更多）请求并最大化您的连接以下载文件。分段技术可确保您的互联网连接带宽被适当地用于下载文件。在以下情况下， IDM(IDM)可以提高下载速度或缩短下载时间：
- 文件的主机服务器拥塞
- 服务器有下载速度限制
- 有太多人同时下载同一个文件
请注意，Internet 下载管理器(Internet Download Manager)( IDM ) 不会提高您的 Internet 速度或提高网络性能。该应用程序下载文件的速度可能比您的网络浏览器快，但下载速度不能超过您的连接能力。
如果您的连接的最大下载速度为 2 MBps ，则(MBps)IDM无法以 2.1 MBps或更高的速度下载文件。事实上，如果您的浏览器可以利用网络的下载速度，您就不需要IDM 。
测试 IDM
我们使用IDM和 Google Chrome 的内置下载器从Google Drive和Dropbox下载了一个 23.9 MB 的视频文件。所有文件都在同一分钟内下载到同一台计算机、同一Wi-Fi网络上。(Wi-Fi)连接速度可能会有一些波动，但这应该是最小的。
Chrome在 19.21 秒和 17.45 秒内从Google Drive和Dropbox下载了视频文件。我们将IDM集成到Chrome并在 11.38 秒（ (Chrome)Google Drive）和 13.72 秒（Dropbox ）内下载了相同的文件。
我们对托管在Google Drive(Google Drive)和Dropbox中的音乐文件 (6.94) 进行了另一次比较。IDM在 2.44 秒 ( Google Drive ) 和 2.82 秒 ( Dropbox ) 内下载了文件。使用 Chrome 的本地下载器，下载相同的文件需要 6.18 秒（Google Drive）和 6.42 秒（Dropbox）。
IDM对其他文件类型（ (IDM)PDF、EXE、ZIP文件等）的下载时间也最短。因此，很明显Internet 下载管理器(Internet Download Manager)提高了下载速度并缩短了下载时间。
影响文件下载速度的因素(File Download Speed)
Internet 下载管理器(Internet Download Manager)( IDM ) 下载文件所需的时间取决于以下因素：
- 连接强度：(Connection Strength:)您的ISP的连接性能（在您所在地区）会影响IDM中的文件下载速度。如前所述，IDM下载速度不能超过您网络的容量。断开某些设备与路由器的连接以释放带宽。如果您仍然没有获得您支付的广告网络速度，请(aren’t getting the advertised network speed you paid for)联系您的ISP。我们还建议您阅读我们关于无需付费即可( without paying for it)获得更快(getting faster )互联网(internet)的教程。
- 一天中的时间：(Time of the Day:)当更少的人同时从服务器请求相同的内容时，您将获得更快的下载速度。午夜(Midnight)或清晨是享受高速下载的最佳时段。
- 活跃(Active Internet Apps:)的 Internet 应用程序：在前台或后台使用 Internet 的程序过多会降低 IDM 的下载速度。关闭(Closing)不必要的应用程序或浏览器选项卡可以加快下载速度。同样(Likewise)，暂停其他正在进行的占用大量带宽的活动（在线游戏、视频流等）可以提高下载速度。
- Host Website/Server:几乎不可能以相同的速度从不同的网站下载文件（或不同的文件）。文件(File)下载速度会因服务器技术、服务器配置、数据传输技术等而异。
一些网站故意限制普通/非付费用户的下载带宽，而高级/付费用户享受无上限的下载速度。
- 您正在使用的 IDM 版本：(The IDM Version You’re Using:) IDM是一款付费应用程序，提供 30 天的免费试用期。一台计算机一年的IDM许可证费用为 11.95 美元，而终身许可证费用为 24.95 美元。根据 IDM(According to IDM)的说法，注册版比试用版更好地利用您的带宽来获得更快的下载速度。注册 IDM(Registered IDM)还解锁了“下载逻辑优化器(Download Logic Optimizer)”，进一步提升文件下载。
新的 IDM(New IDM)版本/构建通常附带新功能和错误修复，以提高下载速度和性能。选择菜单栏上的帮助，然后选择(Help)检查更新以更新 IDM(Check for updates to update IDM)。
配置IDM以获得最佳下载性能(Optimum Download Performance)
本节介绍调整 Internet 下载管理器的连接设置以提高下载速度和性能的方法。这些设置可确保IDM在从 Internet 下载文件时充分利用您的连接。
1.关闭限速器(1. Turn Off Speed Limiter)
IDM有一个“限速器”，可让您设置文件的最大下载速度。禁用该功能可确保IDM利用所有可用的连接带宽来下载文件。
打开Internet 下载管理器(Internet Download Manager)，前往下载(Downloads)选项卡，选择Speed Limiter，然后选择关闭(Turn off)。

Does Internet Download Manager Increase Download Speed?
Internet Downloаd Manager (IDM) is a popular free download manager for Windows computers. The developers claіm that IDM incrеases your device’ѕ download speed uр to five times. Іs this a marketing gimmick?
We’ll walk you through IDM’s download process and compare its download speed for different files across different platforms. This post also covers factors affecting IDM’s download speed and how to configure the app for improved download performance.
5x Download Speed Increase: How’s That Possible?
Internet Download Manager uses a “Dynamic File Segmentation” technology to speed up file download on your computer. It splits a file into eight segments and downloads them individually.
The white bars in the download progress area represent the segments, while the blue bar highlights the downloaded section progress of each segment. IDM separates each segment with a pink line.
When IDM successfully downloads a file segment, it reassigns the connection to help other segments. IDM halves a slow-performing segment and reduces the time required to request the segment from the host server. IDM (re)assembles all downloaded segments into a single file and saves it on your computer.
Summarily, IDM makes eight different requests to the same server to download the eight segments of the file. Eight heads are better (and faster) than one, right?
Think of IDM’s download segmentation technology as sending eight store employees to handpick 32 boxes of milk from a truck. They can each carry four boxes and get the job done quicker than assigning the task to one employee.
IDM uses a similar approach. It sends eight (or more) requests to the servers and maximizes your connection to download files. The segmentation technology ensures that your internet connection’s bandwidth is properly utilized to download files. IDM can boost download speed or shorten download time if:
- The file’s host server is congested
- The server has a download speed limit
- There are too many people downloading the same file concurrently
Note that Internet Download Manager (IDM) doesn’t boost your internet speed or improve network performance. The app might download a file faster than your web browser, but the download speed cannot exceed your connection’s capability.
If your connection has a 2 MBps maximum download speed, IDM cannot download files at 2.1 MBps or higher. In fact, you don’t need IDM if your browser can utilize your network’s download speed.
Putting IDM to the Test
We downloaded a 23.9 MB video file from Google Drive and Dropbox using IDM and Google Chrome’s built-in downloader. All files were downloaded on the same computer, on the same Wi-Fi network, within the same minute. There could be some fluctuation in connection speed, but that should be minimal.
Chrome downloaded the video file from Google Drive and Dropbox in 19.21 seconds and 17.45 seconds. We integrated IDM to Chrome and downloaded the same file in 11.38 seconds (Google Drive) and 13.72 seconds (Dropbox).
We ran another comparison on a music file (6.94) hosted in Google Drive and Dropbox. IDM downloaded the file in 2.44 seconds (Google Drive) and 2.82 seconds (Dropbox). Using Chrome’s native downloader, downloading the same file took 6.18 seconds (Google Drive) and 6.42 seconds (Dropbox).
IDM also had the shortest download time for other file types (PDF, EXE, ZIP files, etc.). So, it’s clear that Internet Download Manager increases download speed and shortens download time.
Factors Affecting File Download Speed
The time it takes Internet Download Manager (IDM) to download a file will depend on these factors:
- Connection Strength: Your ISP’s connection performance (in your region) impacts file download speed in IDM. As mentioned earlier, IDM download speed cannot go beyond your network’s capacity. Disconnect some devices from your router to free up bandwidth. Contact your ISP if you still aren’t getting the advertised network speed you paid for. We also recommend reading our tutorial on getting faster internet without paying for it.
- Time of the Day: You’ll get accelerated download speed when there are fewer people simultaneously requesting the same from the server. Midnight or early morning are some of the best periods to enjoy high-speed downloads.
- Active Internet Apps: Having too many programs using the internet in the foreground or background can slow down IDM’s download speed. Closing unnecessary applications or browser tabs can speed up download speed. Likewise, pausing other ongoing bandwidth-heavy activities (online gaming, video streaming, etc.) can boost download speed.
- Host Website/Server: It’s almost impossible to download a file (or different files) from various websites at the same speed. File download speed will vary based on the server technology, server configurations, data transfer technology, etc.
Some websites intentionally limit download bandwidth for regular/unpaid users, while premium/paid subscribers enjoy uncapped download speeds.
- The IDM Version You’re Using: IDM is a paid app that offers a 30-day free trial period. A year’s license of IDM for one computer costs $11.95, while the lifetime license costs $24.95. According to IDM, the registered version better utilizes your bandwidth for faster download speed than the trial version. Registered IDM also unlocks the “Download Logic Optimizer” that further boosts file download.
New IDM versions/builds often ship with new features and bug fixes that enhance download speed and performance. Select Help on the menu bar and select Check for updates to update IDM.
Configure IDM for Optimum Download Performance
This section covers ways to tweak Internet Download Manager’s connection settings to improve download speed and performance. These settings ensure that IDM fully utilizes your connection when downloading files from the internet.
1. Turn Off Speed Limiter
IDM has a “Speed Limiter” that allows you to set a maximum download speed for files. Disabling the feature ensures IDM utilizes all available connection bandwidth to download files.
Open Internet Download Manager, head to the Downloads tab, select Speed Limiter, and select Turn off.
2. Select High Speed Connection Type
Configuring IDM to use the best connection type can also improve download speed and performance.
Open IDM, select Downloads on the menu bar, and select Options.
Head to the Connection tab, select the Connection Type/Speed drop-down menu, and select High speed: Direct connection (Ethernet/Cable) / Wi-Fi / Mobile 4G / other. Select OK to save the changes and close the dialog window.
3. Increase or Decrease Bandwidth Connection Type
IDM can split your file up to 32 segments and download each segment using different connections. The default connection limit is eight, but you crank it up to 32 anytime. Increasing the maximum connection limit (to 16 or 32) can increase IDM’s download speed on a broadband connection.
Conversely, reduce the number of simultaneous connections for dial-up or modem connections. Downloading files over too many connections on a dial-up link can stress the website server and reduce download speed. Here’s how to adjust IDM’s maximum connection limit:
Launch IDM and select Options on the toolbar.
Open the Connection tab and select your preferred connection limit in the Default max. conn. number drop-down menu. Select OK to save the changes.
Faster Downloads with IDM
Using a download accelerator is a proven trick to getting faster upload and download speeds in Windows 10. At its core, Internet Download Manager (IDM) is a download manager that efficiently utilizes your connection bandwidth to download files. Maybe not up to 5 times faster than your web browsers, but it sure does a better job. With IDM, you’ll enjoy accelerated download speeds and advanced features like Scheduled Downloads, Automatic Virus Checks, etc.
