The newest NAASC VM Host (naasc-vs-2) often shows over 100 TCP retransmissions per second when doing iperf3 tests. Other nodes like naasc-vs-3 and naasc-vs-4 do not show these at allshow 0 TCP retransmissions per second. While I can't say these TCP retransmissions are indicative of a problem, they could become a problem with increased load and they certainly will make debugging more difficult when there is a problem. I suggest the reason for these TCP retransmissions be found and resolved.
