我构建了一个新的文件服务器，它应该远远超出其用途。它有 2 个 Intel(R) Xeon(R) CPU E5-2660 v3，128GB 内存，它通过 Intel X540T2 网卡运行 LCAP 到 Netgear GS752TP 交换机。我们的路由器是 Ubiquiti EdgeMax
当我尝试向其传输 1GB 数据时，速度保持在 12MBps 左右。我曾看到它达到 25MBps，但甚至降到 500kBps。两次都是短时间内的。
我进行了两次iperf测试，一次在末尾使用了“-u -b 1000m”，另一次什么都没做。我将在下面发布结果。
我的问题是，为什么这种传输在所有 GB 设备中都如此缓慢，而且是硬连线的？可能是配置错误？
我感谢您给我的任何建议。

答案1
如果我理解正确的话，在其中一个桌面上，rsync、Windows 资源管理器或 robocopy.exe 报告的速度为 12Mbps。至少一个连接上有 37% 的数据包进入 bitbucket。我很惊讶它仍然能够超过半千兆位。这真是太了不起了。从传输速度慢的主机，ping -s 60000在 Linux 或ping -t -l 60000Windows 上运行带有非常大数据包的 ping。需要确定它是客户端上的以太网连接还是 NAS 上的以太网连接。还要查看交换机上的丢帧统计信息。速度慢的机器是通过 WiFi 连接的吗？

您的数据中最低速度约为 222Mbps。该数据中哪里显示 12MegaBytesPerSecond / 96MegaBitsPerSecond？
