使用 Tor 浏览器有时会比其他浏览器慢。
The Tor network has over a million daily users, and just over 6000 relays to route all of their traffic, and the load on each server can sometimes cause latency. And, by design, your traffic is bouncing through volunteers' servers in various parts of the world, and some bottlenecks and network latency will always be present.
For the much more in-depth answer, see Roger's blog post on the topic and Tor's Open Research Topics: 2018 edition about Network Performance.
也就是说， Tor 比以前快的多了，你未必会注意到和其它浏览器相比的速度变化。
