在我的 Arch Linux 机器上,我选择性地慢速连接到某些特定资源,例如:Arch 存储库(100 KiB/s,最高)、Minecraft 服务器或任何其他东西 - 我找不到模式。同时,我可以双倍速度观看 1080p 的 YT 视频,无延迟; Steam游戏正在以正常速度下载,我的Steam游戏的ping值约为70。为什么这样?
我在家里找到了另外两根电缆,我尝试了一下,但没有任何结果。
除了我的 PC 之外,我还有一台运行 Arch Linux 的笔记本电脑。我在上面测试了电缆,但再次没有结果。所以我尝试过 WiFi 网络共享,效果很好:下载更新时速度不错,MC 服务器中的 ping 也不错。遗憾的是,我的电脑没有 WiFi 适配器。
会是什么呢?我真的很沮丧。我没有任何线索。我的 ISP 一直说他们不会减慢任何连接(除非是黄金时段的洪流流量)。
这是什么消息显示我通过以下方式连接的 USB 端口:
