Also looks bad to me.

We seem to be a bit worse than the Xenomai 3 results. But the results 
are not great on Xenomai 3 either.

Xenomai3 Kernel 6.18:
https://gitlab.com/Xenomai/xenomai-images/-/jobs/15351736635
WCL: 123.148

Xenomai3 Kernel 6.12 (last weekly running long term run):
https://gitlab.com/Xenomai/xenomai-images/-/jobs/15308563317
WCL 137.195

The oldest Pipeline I was able to find is 11 Month old:
https://gitlab.com/Xenomai/xenomai-images/-/jobs/11042799343
WCL: 124.430

Best,
