Checked a bit more with CONFIG_HZ_100 and CONFIG_PREEMPT_NONE: the same.

Filling rate with vm.dirty_ratio=0 is 1 MB/s (with periodic stalls of everything).

If I set vm.dirty_ratio to 1, it raises to 40 MB/s (stable). Long page faults when loading programs are present as well.

Was testing with only 200 MB (of 1.5G) of memory filled.
