Comcast Corp said on Monday that file transfers on peer-to-peer networks such as BitTorrent may be delayed by bandwidth management technology, but it denied blocking access to any applications or content. As the second-largest high-speed Internet provider in the United States with 11 million customers, any move by Comcast to favor or block certain types of content moving over its network would be extremely controversial as it would be seen as flouting 'net neutrality.'

Net Neutrality is the principle of allowing all content that flows over an Internet service provider's (ISP) network to be treated equally without any preference. Although it is not law, it is supported by a wide range of pressure groups and businesses concerned that ISPs will start charging to prioritize the delivery of users content. The Associated Press reported over the weekend that it had carried out experiments across the country proving that Comcast prevented some users from uploading content to peer-to-peer networks, including BitTorrent. Such networks are used by consumers to share large quantities of files such as music, videos and photographs.

当您使用迅雷下载一个文件的时候，这个文件已经保存在您机器上那部分数据会被传输给其他需要的雷友，帮助他们提升下载速度，这是需要临时使用您的上传带宽的，在不同的网络条件下它们的带宽不相同，如果您遇到上传速度过高，影响您下载时的网页浏览的话，您就需要针对性的进行上传速度设置。这个设置是指上传速度最大值。
（当然，我们推荐带宽较高的用户不限制上传速度，因为从迅雷的下载原理来说，你不上传给别人，那么你下载的时候别人也不会传数据给你）

1、首先，打开设置最大上传速度的窗口，点击配置，选择连接选项卡，并且在"将上传速度限制为"上打钩。
2、然后根据您的带宽选择你合适的上传速度。
512kbit应是 10
1mbit应是 20
2mbit应是 40
3mbit应是 60
4MB及以上带宽的用户我们建议您不要限制上传速度。（如果以上值您认为不合适，您可以自行修改。）
设置完成后，点击"确定"，即可进行更改。
