Recall the host config is VSWITCH_VHOST_CPU_MAP = [4,5,8,11] and here PROX observed interrupts on NUMA 0 cores 2, 7, 14, 16, (many) 17 and 18 in the 10-50usec range. Eventually, all cores 1-15 experienced 2 events in the 10-50usec range (when PROX was allowed to run for about 30 minutes after the 60 second test).
The data plane measurements indicate one second with 45 frame losses (see the very bottom of the figure). Message logging on Nodes 4 and 5 indicated nothing during the 60 sec iPerf3 test. Below we see an except of the iPerf3 output from the Server, showing the single second with 45 packet losses.
