是用这个方式建立的安装盘吗？

@cxytz01 不管是三指还是单指，都是可以的

是在 2.4G wifi 吗？

usb 3.0 不合格的屏蔽会消灭附近小范围的 2.4G wifi/BT

6 代 CPU ？

iperf3 at 40Gbps and above
Achieving line rate on a 40G or 100G test host often requires parallel streams. However, using iperf3, it isn't as simple as just adding a -P flag because each iperf3 process is single-threaded, including all streams used by that iperf process for a parallel test. This means all the parallel streams for one test use the same CPU core. If you are core limited (this is often the case for a 40G host and it's usually the case for a 100G host), adding parallel streams won't help you unless you do so by adding additional iperf3 processes which can use additional cores.

Note that it is not possible to do this using pscheduler to manage iperf3 tests, so this is typically better suited to lab or testbed environments.

To run multiple iperf3 processes for a testing a high-speed host, do the following:

Start multiple servers:

iperf3 -s -p 5101&; iperf3 -s -p 5102&; iperf3 -s -p 5103 &
and then run multiple clients, using the "-T" flag to label the output:

iperf3 -c hostname -T s1 -p 5101 &;
iperf3 -c hostname -T s2 -p 5102 &;
iperf3 -c hostname -T s3 -p 5103 &;
Also, there are a number of additional host tuning settings needed for 40/100G hosts. The TCP autotuning settings may not be large enough for 40G, and you may want to try using the iperf3 -w option to set the window even larger (e.g.: -w 128M). Be sure to check your IRQ settings as well.

有点像掉盘了，正常一瞬后，主控不再报告块设备的描述信息了，导致卷没有继续加载，只留下光秃秃一个主控在哪。

没有详细的日志信息露出表明，但也可以猜测是检测卷不干净，有进入 fsck 修复阶段后锁定了卷，这种情况可能要等几分钟。

你在用 C 转 A 的转接器吗？
