Thanks, seems like significant changes were made in the smp department, let's hope they work out. The plot really does look stunning, strangly (?) not on other machines. https://www.osadl.org/Latency-plot-of-system-in-rack-4-slot.qa-latencyplot-r4s7.0.html https://www.osadl.org/Latency-plot-of-system-in-rack-4-slot.qa-latencyplot-r4s8.0.html No idea what those plots tell about real world usage. It's good to get another set of patches though.
