Out of curiosity I tried to find results for D510 and D525 boards - they both are mentioned in the list of tested systems.
This is D510: https://www.osadl.org/Latency-plot-of-system-in-rack-1-slot.qa-latencyplot-r1s4.0.html?latencies=&showno=&slider=228 This is D525: https://www.osadl.org/Latency-plot-of-system-in-rack-4-slot.qa-latencyplot-r4s7.0.html?latencies=&showno=&slider=228 Where did they get 4 cores? From hyperthreading? Do I understand correctly that disabling hyperthreading should improve latency figures? Then number of cores for all Intel cpus should be divided by 2 to get the actual number. Hmm, does not look very impressive, knowing that I got <10 us latency on D525, but here it seems to be at around 20 for vast majority of samples.
