FreeNAS +慢速转移？

Question

我构建了一个新的文件服务器，它的目的应该是过度构建的。它有2个英特尔(R) Xeon(R) CPU E5-2660 v3，内存128 to，并通过英特尔X540T2网卡运行GS752TP交换机。我们的路由器是一个Ubiquiti EdgeMax

当我试图向它传输1GB的数据时，速度保持在12 12MBps左右。我看到它达到了25 25MBps，但甚至降到了500 25MBps。都是短短的阵阵。

我运行了两个iperf测试，一个在末尾使用"-u -b 1000 m“，另一个没有使用。我将张贴下面的结果。

我的问题是，为什么在所有GB设备和硬连线的情况下，这种传输会如此缓慢？会不会有错配置的东西？

我很感激你给我的任何建议。

Answer 1

如果我理解，在其中一个桌面上，rsync、Windows或robocopy.exe正在报告12 12Mbps。至少有一个连接上的数据包中有37%进入bitbucket。我很惊讶它还能超过半千兆位。这太惊人了。从主机慢速传输，运行一个带有非常大数据包的ping，ping -s 60000在Linux上运行，ping -t -l 60000在Windows上运行。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。还可以查看丢弃帧统计信息的开关(Es)。慢速机器是通过WiFi连接的吗？

数据中的最低速度约为222 about。在这些数据中，12 12MegaBytesPerSecond / 96MegaBitsPerSecond在哪里？
