Readynas NV+ v2 NAS 的 LAN 连接速度极慢

Readynas NV+ v2 NAS 的 LAN 连接速度极慢

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。

eth0 的设置和其他信息

网络设置:
光纤 -> 媒体转换器 CTSystem HET-3012 -> Zyxel P-2812 路由器 -> Linksys E3000 作为交换机 -> NAS
