DELL 万兆 X550T 网卡 debian 连接交换机 10G，但 iperf 最高只能到 1G，信息如下。 哪里出问题了？

我的话会换 iperf3 先看看

iperf 是 1GB?
ethtool Speed: 10000Mb/s |

axiauk OP 是的，不知为何实际只有标准的千兆网卡速度。 在 NFS 和 SMB 上也是标准的千兆。

axiauk OP 折腾两天无果。之前装 windows 10 下 iperf3 都没问题的。难道是姿势不对，默认配置有问题？
下面这条命令不知道是干嘛的 # ethtool -g enp2s0f0 Ring parameters for enp2s0f0: Pre-set maximums: RX: 4096 RX Mini: 0 RX Jumbo: 0 TX: 4096 Current hardware settings: RX: 512 RX Mini: 0 RX Jumbo: 0 TX: 512 |

我比较奇怪，网卡插在 pcie2.0 8x 的插槽，每次开机都只能运行在 2x 模式下，显示 10G，实际 3G，重启之后才会运行在 8x 模式。

axiauk OP 已经解决了。但是没搞明白。NUC9 接了一个千兆网卡管理口 连接 AMT （ 192.168.1.10 ）万兆（ 192.168.1.7 ），安装 OMV 配置这两个网卡和 IP，删掉 千兆网卡带宽就正常了。 之前出问题也怪，iperf 无论主 /客 都是到 192.168.1.7 流量只有千兆，难道都通过 192.168.1.10 中转？
