1) disable hyperthreading and running a single core
Seems like the latency problem is due to enabled hyperthreading.
I reran the latency tests with hyperthreading disabled and the latencies
stay below 20 microseconds now. This is with 1 and 8 cores. So
yesterday.
Thanks a lot for your help,
Julian

Thanks for your pointer to hwlatdetect and possible SMI issues.
It looks like the hwlatdetect script is not working with the latest
kernel anymore. However

Hi folks,
after installing Xenomai 3.0.5/kernel 4.9.38 following [1] on our Dell
Precision 5820 machine (Intel Xeon W-2145), there are high latencies
when the system is at rest. When starting a stress test via `stress -v
-c 8 -i 10 -d 8`, the latency goes down (see terminal output below).
