 | 3 VYSE 2020-07-13 09:06:57 +08:00 via Android iperf 是 1GB? ethtool Speed: 10000Mb/s |
 | 4 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。 # iperf3 -c 192.168.1.3 Connecting to host 192.168.1.3, port 5201 [ 5] local 192.168.1.10 port 43088 connected to 192.168.1.3 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 113 MBytes 949 Mbits/sec 0 1.45 MBytes [ 5] 1.00-2.00 sec 110 MBytes 923 Mbits/sec 0 1.45 MBytes [ 5] 2.00-3.00 sec 110 MBytes 923 Mbits/sec 0 1.45 MBytes [ 5] 3.00-4.00 sec 110 MBytes 923 Mbits/sec 0 1.46 MBytes [ 5] 4.00-5.00 sec 110 MBytes 923 Mbits/sec 0 1.46 MBytes [ 5] 5.00-6.00 sec 110 MBytes 923 Mbits/sec 0 1.96 MBytes [ 5] 6.00-7.00 sec 110 MBytes 923 Mbits/sec 0 1.96 MBytes [ 5] 7.00-8.00 sec 109 MBytes 912 Mbits/sec 0 1.96 MBytes [ 5] 8.00-9.00 sec 111 MBytes 933 Mbits/sec 0 1.96 MBytes [ 5] 9.00-10.00 sec 110 MBytes 923 Mbits/sec 0 1.96 MBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 1.08 GBytes 925 Mbits/sec 0 sender [ 5] 0.00-10.00 sec 1.07 GBytes 923 Mbits/sec receiver |
| 5 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 |
 | 6 yelocat 2020-07-13 14:40:19 +08:00 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。 |
| 7 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？ |
