In this PROX which essentially measures the duration of a 1 nanosecond heartbeat, it is clear that some process is producing fairly frequent interrupts that cause delays in the 10-50 usec and 50-100usec range on core 6. Also, Core 11 has some interrupts in the 10-50usec range: it is important to check this when the VSPERF deployment is running (for . In the iPerf3 testing below, the Max MTU packets used have 1.2144 usec serialization delay, so a 10 usec interruption would affect approximately 12 frames.
For example, the BSwLV OVS-Vanilla config has:
