YouTube已经存在 15 年了，但没有其他以视频为中心的网站拥有与这个庞大的平台进行有效竞争的手段。虽然Facebook等公司正试图将IGTV定位为竞争，但要成为大多数人的可行选择还有很长的路要走。
提高 YouTube 缓冲(Improve YouTube Buffering)、性能(Performance)和速度(Speed)
那里有很多视频流媒体网站，YouTube毫无疑问是这个星球上使用最多的视频网站。但最近我开始遇到YouTube缓冲问题。我有一个相当不错的连接，但是，YouTube 运行缓慢(YouTube was running slow)(YouTube was running slow)，视频需要永远缓冲。当您尝试观看非常重要的内容时，这可能会令人沮丧。除了YouTube，所有其他流媒体网站都运行良好——例如Metacafe、Vimeo等。所以我决定进行一些故障排除，看看我是否可以解决这个问题并改善YouTube的缓冲、性能和速度。
如何让YouTube视频加载更快
就目前而言，YouTube是我们目前内容的最佳选择，那么当YouTube上的视频开始定期缓冲时我们该怎么办？
在许多情况下，缓冲和整体性能问题与您的互联网连接速度无关。有时，这些因素是完全不同的，这就是为什么我们决定讨论其他问题，说明您的视频加载困难的原因。
本文将解释在观看YouTube视频时减少问题的几种方法。全部尝试一下，看看哪一个效果最好，或者你。
- YouTube DNS
- 更改视频质量
- 启用限制可预留带宽
- 防火墙异常技巧
让我们更详细地讨论这种情况。
1] YouTube DNS
在流式传输视频时改善缓冲的最佳方法之一是将您的DNS更改为(DNS)Google提供的DNS 。在某些情况下，使用这个OpenDNS会很有帮助。(OpenDNS)
好的，所以在这里要做的第一件事就是访问控制面板(Control Panel)，为此，您必须首先通过搜索框搜索控制面板(Control Panel)，然后从那里继续前进。打开面板后，从列表中选择网络和 Internet(Network and Internet)，然后单击网络和共享中心(Network and Sharing Center)。
到达那里的另一种方法是右键单击任务栏上的Wi (Taskbar)-Fi(Wi-Fi)连接图标，然后选择打开网络(Open Network)和 Internet(& Internet)设置。现在，从左窗格中单击Change adapter settings，然后从那里右键单击其中一个网络，并确保双击Internet Protocol version 4 (TCP/IPv4)。
接下来，找到“使用(Use)以下DNS服务器地址”部分，然后选择它。从那里开始，以下选项应如下所示：
- 首选 DNS 服务器：208.67.222.222
- 备用 DNS 服务器：208.67.220.220
最后，单击确定按钮并重新启动计算机以在您再次访问 YouTube 时查看更改。
2]改变视频质量
提高YouTube性能的另一种方法是更改视频质量。对于许多人来说，默认是 720p 高清或 1080p 高清。在某些情况下，默认值甚至可能设置为 4K。根据您的互联网连接速度，加载高质量视频可能需要一段时间。
为确保更好的性能，只需降低视频质量。480p 很好，因为它保持了不错的质量，因此，它是可观看的，并且应该比它前面的任何东西加载得更快。
3]启用限制(Enable Limit)可保留带宽
您(Did)知道吗，在某些情况下，Windows 10会保留一部分带宽用于下载更新等。这很重要，是的，但该功能并未在商店中设置，因为事情可能会发生变化。
为了享受您的互联网连接所提供的全速，我们将不得不禁用此功能。我们可以通过单击搜索图标来执行此操作，然后键入 gpedit.msc。从搜索结果中打开此工具，然后立即导航至：
LOCAL COMPUTER POLICY > COMPUTER CONFIGURATION > ADMNISTRATIVE TEMPELATES > NETWORK > QOS PACKET SHEDULER > LIMIT RESERVABLE BANDWITH.
从那里，寻找显示限制可保留带宽(Limit reservable bandwidth)(Limit reservable bandwidth)的选项，并立即启用它。之后，请务必将限制设置为 0，然后点击Apply > OK。最后，继续并重新启动计算机并测试YouTube加载视频的速度是否比以前快得多。
4]防火墙异常技巧
某些 ISP(Certain ISP)倾向于限制缓存视频的服务器的带宽，从而导致性能问题。这个想法是找到相关的 IP 范围并通过Widows 防火墙(Widows Firewall)阻止它们。在某些情况下，走这条路应该会提高性能。您可以这样做：
- 转到开始菜单并输入 CMD
- 然后右键单击(Right-click)并单击以管理员身份运行(Run)
- 然后复制并粘贴以下命令
netsh advfirewall firewall add rule name="TWCYouTubeFIX" dir=in action=block remoteip=173.194.55.0/24,206.111.0.0/16 enable=yes
您现在需要重新启动计算机，然后再尝试查看是否一切正常。另外，如果要删除规则，请在CMD中键入以下命令：
netsh advfirewall firewall delete rule name="TWCYouTubeFIX”
这些选项中的至少一个应该能够更快地加载YouTube视频，因此我们建议您尝试所有选项，看看哪一个效果最好。

Improve YouTube Buffering, Performance & Speed
YouTube has been around for 15-years, and yet no other video-centric website possesses the means to compete effectively with this mammoth platform. While the likes of Facebook is trying to position IGTV to compete, it has a long way to go before it can become a viable option for most.
Improve YouTube Buffering, Performance & Speed
There are a lot of video streaming websites out there, and YouTube is without a doubt the most used video website on this planet. But recently I started having issues with YouTube buffering. I have a pretty decent connection, but still, YouTube was running slow and the videos taking forever to buffer. This can be frustrating when you are trying to watch something really important. Except for YouTube, all the other streaming sites worked just fine – for example, Metacafe, Vimeo, etc. So I decided to do some troubleshooting to see if I could resolve this problem and improve YouTube buffering, performance, and speed.
How to make YouTube videos load faster
As it stands, YouTube is our best bet for content for the time being, so what do we do when videos on YouTube begins to buffer on a regular basis?
In many cases, buffering and overall performance problems have nothing to do with the speed of your internet connection. At times, the factors are quite different, which is why we’ve decided to discuss alternative issues as to why your videos are having a hard time loading.
This article will explain several ways to reduce problems when watching YouTube videos. Try them all to see which one works the best or you.
- YouTube DNS
- Change the video quality
- Enable Limit reservable bandwidth
- Firewall Exceptions Trick
Let us discuss this situation in more detail.
1] YouTube DNS
One of the best ways to improve buffering when streaming videos, is by changing your DNS to one offered by Google. Using this OpenDNS, in some cases, can help a great deal.
OK, so the first thing to do here, is to visit the Control Panel, and to do this, you must first search for Control Panel via the search box and move forward from there. After opening the panel, select Network and Internet from the list, then click Network and Sharing Center.
Another way to get there is by right-clicking on the Wi-Fi connected icon on the Taskbar, then select Open Network & Internet settings. Now, from the left pane, click on Change adapter settings, then from there, right-click on one of the networks, and be sure to double-click Internet Protocol version 4 (TCP/IPv4).
Next, seek out the section, Use the following DNS server addresses, and select it. From there, the following options should look like this:
- Preferred DNS server: 208.67.222.222
- Alternate DNS server: 208.67.220.220
Finally, click on the OK button and restart the computer to see the changes whenever you visit YouTube again.
2] Change the video quality
Another way to improve performance on YouTube is to change the quality of videos. For many, the default is either 720p HD or 1080p HD. In some cases, the default might even be set at 4K. Depending on the speed of your internet connection, it may take a while to load videos at high quality.
To ensure better performance, just decrease the video quality. 480p is nice since it keeps a decent amount of quality, therefore, it is watchable and should load much faster than whatever comes ahead of it.
3] Enable Limit reservable bandwidth
Did you know that in some cases, Windows 10 will reserve a portion of your bandwidth for the purpose of downloading updates among other things. This is important, true, but the feature is not set in store because things can change.
In order to enjoy the full speed of what your internet connection has to offer, we will have to disable this feature. We can do this by clicking on the search icon, then type gpedit.msc. Open this tool from the search results, then right away, navigate to:
LOCAL COMPUTER POLICY > COMPUTER CONFIGURATION > ADMNISTRATIVE TEMPELATES > NETWORK > QOS PACKET SHEDULER > LIMIT RESERVABLE BANDWITH.
From there, look for the option that says Limit reservable bandwidth, and enable it right away. After that, be sure to set the limit to 0, then hit Apply > OK. Finally, go on ahead and restart your computer and test if YouTube is loading videos much faster than before.
4] Firewall Exceptions Trick
Certain ISP tends to throttle bandwidth from the server that caches videos which caused performance issues. The idea is to find the relevant IP range and block them via Widows Firewall. Going down this road should improve performance in some cases. This is how you can do it:
- Go to Start Menu and type in CMD
- Then Right-click and click on Run as administrator
- Then copy and paste the following command
netsh advfirewall firewall add rule name="TWCYouTubeFIX" dir=in action=block remoteip=173.194.55.0/24,206.111.0.0/16 enable=yes
You will now want to restart the computer before attempting to see if everything works accordingly. Also, if you want to remove the rule, then type the following command in CMD:
netsh advfirewall firewall delete rule name="TWCYouTubeFIX”
At least one of these options should enable faster loading of YouTube videos, so we recommend trying them all to see which one works the best.
