我正在 Ubuntu 20.04 上进行实验。它运行良好，但速度非常慢。这是一个使用广泛使用的 torrent（是 的别名）transmission-daemon的示例：tmrtransmission-remote
$ tmr -a "https://releases.ubuntu.com/20.10/ubuntu-20.10-desktop-amd64.iso.torrent"
localhost:9091/transmission/rpc/ responded: "success"
即使 5 分钟后，下载速度仍然低于 20 kB/秒：
$ tmr -l
ID Done Have ETA Up Down Ratio Status Name
1 0% 2.98 MB 1 days 0.0 19.0 0.0 Downloading ubuntu-20.10-desktop-amd64.iso
Sum: 2.98 MB 0.0 19.0
但是，输入相同的 torrent 文件后，transmission-gtk下载速度几乎立即达到数百 kB/秒：
以下是设置转储。下载速度限制已停用，这不是原因。还能是什么？
$ transmission-daemon --dump-settings

答案1
事实证明，transmission-daemon它遵守了 9 kB/秒的某种默认下载限制。该程序实际上忽略了配置文件中的speed-limit-down 和参数。speed-limit-down-enabled
这些设置只能通过 Web 界面进行修改。访问http://localhost:9091，单击齿轮图标并选择总下载速率>无限，然后享受适当的下载速度。
