装了ESXi8，发现了第一个问题，华硕Z490-A自带的Interl I225-V 2.5G网卡只能被识别成100M。幸亏另加的英特尔I350T2X1双网口网卡能被正确识别成1000M的，而且显示支持SR-IOV，但是设置了好多次SR-IOV,重启后模拟网卡数量就会跳回0个，无法正确启用。不知道是ESXi版本问题还是别的什么原因
因为低配高价，放弃升级群晖NAS的想法 转而 来玩玩ESXi 8.0吧
趁着这个机会，把所有ESXi的虚拟机和路由器的速度都测了一遍，果然只要把虚拟机的网络适配器改为英特尔I350T2X1网卡的端口组，速度马上就从百兆变为千兆。
这个时候想到测试一下我的群晖DS418play到路由器的速度，结果一下子还找不到iperf3在Synology的应用，网上又编译的spk是针对DSM6.3的，而且无法下载，DSM7又提到的一般是用Docker运行，而我的群晖DS418play无法运行Docker。
几经搜索，发现了群晖的Diagnosis Tool工具，里面有78个工具，其中就包括iperf3，方法很简单。
-
运行：/var/packages/DiagnosisTool/target/tool/speedtest-cli.py
-
会在结果可以找到Download: 138.89 Mbit/s；Upload: 63.01 Mbit/s（这是我千兆移动的测试结果）
如果不想使用synogear了， 一个命令就可移除：
sudo synogear remove
