  1. Done: Recreate na-arc-3 so it gets the same performance as other na-arc-* nodes which is apparently at least 10Gb/s. (pmurphy)
    1. 2022-08-11: cloned na-arc-2 and moved the clone to naasc-vs-3 (zbutcher)
    2. 2022-08-11: moved old na-arc-3 to na-arc-3-OLD (thalstea)
    3. 2022-08-11: Renamed the clone to na-arc-3.  We connected it to the swarm successfully, but it had a low connection speed.
    4. 2022-08-11: Changed the model of  na-arc-3's vnet5 interface on naasc-vs-3 from rtl8139 to virtio to match all the other na-arc-* nodes.  Performance was still poor.
    5. 2022-08-11: Changed the MTU of na-arc-3 eth0 to 1500.  This is different than all the other na-arc-* nodes but it was either that or change the p5p1.120 and br97 on naasc-vs-3 from 9000 to 1500 which my have impacted other VM guests on that host.  Performance was now reasonable.  7Gb/s.  I was expecting about 9Gb/s but perhaps the 1500 MTU is affecting performance.
    6. 2022-08-11: Joined na-arc-3 to the swarm and started services (sbooth)
  2.  Done: Launch services on production swarm (sbooth)
    1. 2022-08-11: Joined na-arc-3 to the swarm and started services (sbooth)
  3. Test the production docker swarm with a test web interface. (lsharp)
    1. 2022-08-12: http://almaportal.cv.nrao.edu/
    2. 2022-08-12 krowe: rant tcpdump on all five na-arc-{1..5} nodes tcpdump dst almaportal and then downloaded a datafile wget --no-check-certificate https://almaportal.cv.nrao.edu/dataPortal/2013.1.00226.S_uid___A001_X122_X1f1_001_of_001.tar and with each execution of the wget, I could see the nex na-arc host report the traffic.  This is because the web proxy on almaportal will select the next na-arc node via round-robin.  All five nodes were providing about 6KB/s speeds to cvpost-master.
    3. 2022-08-12 krowe: I did iperf tests from host to host in the entire chain (nangas14 -> na-arc-{1..5} -> almaportal -> cvpost-master) and each step the performance was at least 900Mb/s yet downloading with wget was about 0.06Mb/s.
  4. ask Done: Ask other ARC if they use MTU 9000 on 10Gb. (krowe)
    1. JAO uses MTU of 1500
    2. ESO uses two VM hosts running VMware with 10Gb/s and MTU of 1500
  5. Switch the production docker swarm back to MTU 1500 since the test docker swarm uses MTU 1500 and is performing better?
  6. Fix natest-arc-3 so it's NIC Model is virtio instead of rtl8139
  7. Upgrade production swarm to meet ALMA requirements (16-core, 32GB)
