我有这两个MNPA19-XTR MELLANOX 10GB 以太网网络接口卡
我的两台服务器 1. Dell PowerEdge R900 2. Dell PowerEdge T300
我正在将数据从 R900 复制到 T300
这两台服务器使用这些网卡点对点连接
当我开始数据移动时，速度上升到 320MB/s（大约）并保持 30 秒，然后下降到 0MB/s 并等待 30 秒或更长时间，然后回到 320MB/s（大约）
它只是在 0 到 320MB/s 之间循环，就像在休息一样
在使用这些卡之前，我有千兆以太网卡，并且能够连续获得 100MB/s 的速度，没有任何中断
提前感谢您阅读我的问题
