Hi,

The green ticks on X11 test are interesting - something with a higher
prio than
the SCHED_FIFO max takes the processor away from it and runs for more
than 1 ms.

The only thing that can do that is interrupt routines / back handlers...
(try to find this one)

Disk read looks nice - others looks ...
