我最近在使用 ookla speedtest cli 时获得了以下速度...
$ speedtest
Speedtest by Ookla
Server: ********
ISP: TELUS
Idle Latency: 1.98 ms (jitter: 0.08ms, low: 1.85ms, high: 2.05ms)
Download: 913.40 Mbps (data used: 1.3 GB)
4.96 ms (jitter: 0.86ms, low: 1.47ms, high: 10.53ms)
Upload: 900.51 Mbps (data used: 1.2 GB)
4.99 ms (jitter: 1.25ms, low: 1.52ms, high: 11.40ms)
Packet Loss: 0.0%
最近我的速度下降到了大约 1/2（即~500Mbps）而且我不知道为什么......
我尝试了各种故障排除方法，但目前都无济于事。没什么主意了。
- 重新启动
- 检查了物理电缆。笔记本电脑使用与问题机器相同的电缆/交换机端口获得千兆速度
- 关闭所有 docker 容器和 docker 服务本身，以防某些东西占用了带宽
- 已禁用 ipv6
