Well if the linux-kernel is busy moving memory around, other load - like realtime threads - might have to wait for that to finish.

Could I please attach my .config in this mailing list willing for > help? If you have a closer look you will also see Selected by: COMPACTION [=y] && MMU [=y] || CMA [=n] && HAVE_MEMBLOCK [=y] && MMU [=y] That information can be seen i.e. in "make menuconfig". From there find a way to break the chain that is pulling it in. I guess MMU should stay enabled, so COMPACTION and its "Selected by"s.
