- Why does iperf show 9Gb/s between na-arc-4 (which is on naasc-vs-4) and na-testcarta-2 (which is on naasc-vs-3) when there is only a 1Gb/s link between those two VM Hosts?
- Why does na-arc-3 have such poor network performance to the other na-arc nodes?
- Is putting all the production docker swarm nodes on the same ASIC on the same Fabric Extender of the Nexus switch a good idea?
- When I run ethtool eth0 on nanar-arc-3 as root to get the speed. But when I run ethtool eth0 on nar{1..5} natest-arc-[{1,2,4,5] ..2} as root, the result is just Link detected: yes instead of the full report with speed. Yet natest-arc-3, which has ens3 instead of eth0, shows speed of 100Mb/s?
- Why do natest-arc-{1..3} have 9 veth* interfaces in ip addr show while na-arc-{1..5} don't have any veth* interfaces?
To Do
- Switch the production docker swarm back to MTU 1500. Since the test docker swarm uses MTU 1500 and is performing better.
