DL185 G5 以太网速度较差

我花了大约 20 美元购买了这台服务器，并将其用于我的家庭实验室设置。问题是以太网速度在 LAN 上达到峰值 8MB/s，在互联网上甚至更糟，降至 5MB/s。这通常表明连接速度为 100Mbps，但服务器和路由器都报告了 1000Mbps 的链接。这既拉向服务器，又向外推，从而排除了驱动器速度。加上在 SSD 上的测试。我的电脑将以千兆位速度连接到同一个路由器。我在服务器上使用了相同的电缆，没有任何变化。在内核为 5.3.18-2-pve 的 Debian 上运行 Proxmox。任何想法或建议都将不胜感激

我可以运行这个程序任意长的时间，但这是完全相同的问题。我似乎以某种方式锁定在 100mbps，无论路由器和服务器说链接速度是多少
