我在 Readynas NV+v2 NAS 上遇到上传速度极慢的情况。
速度测量
使用测试时speedtest-cli
我得到以下结果:
Testing download speed........................................
Download: 165.95 Mbits/s
Testing upload speed..................................................
Upload: 0.80 Mbits/s
我期望这条线路上的速度是 300/300,而这也正是我在连接到同一路由器的其他设备上得到的速度。
- 当我测量 NAS 到互联网时,我得到的结果大约是下载速度为 150 Mbps,上传速度为 0.5 Mbps。
- 当我通过 WiFi 将 NAS 测量到连接到 Zyxel 的另一台设备时,速度正常(用 测量
iperf
),大约为 250 Mbps/250 Mbps。 speedtest-cli
当我从连接到 Linksys 的另一台设备运行时,我获得的速度大约为 300/300。
