超级用户阅读器亚当(Adam)想知道DNS服务器是否可能影响下载速度：
I have been experiencing a problem with low download speeds from the Mac App Store. I decided to change my DNS configuration to Google DNS 8.8.8.8 and it started to download over ten times faster on the same Wi-Fi setup. How is this actually possible?
我一直在Mac App Store中遇到下载速度低的问题。 我决定将我的DNS配置更改为Google DNS 8.8.8.8，在相同的Wi-Fi设置下，它开始下载的速度快了十倍。 实际上这怎么可能？

They can have an indirect effect. For example, downloading a file from Akamai:
它们可以产生间接影响。 例如，从Akamai下载文件：
Say you are in Germany. DNS server A resolves you to a French node, the connection is good, and the download is fast. DNS server B resolves you to a U.S. node, the connection is poor, and the download is significantly slower.
假设您在德国。 DNS服务器A将您解析为法语节点，连接状态良好，下载速度很快。 DNS服务器B将您解析到美国节点，连接状况不佳，下载速度明显降低。
Slow DNS queries themselves will not cause your download speed to be slower, but they will cause web pages to wait longer before starting to download.
缓慢的DNS查询本身不会导致您的下载速度变慢，但是会导致网页在开始下载之前等待更长的时间。
