This is also interesting (although I don't know what it really means).
Looking at pmap run against mmfsd I can see what happens after each step:
# baseline
7fffe4639000 59164K 0K 0K 0K 0K ---p [anon]
7fffd837e000 61960K 0K 0K 0K 0K ---p [anon]
I've been exploring the idea for a while of writing a SLURM SPANK plugin
to allow users to dynamically change the pagepool size on a node. Every
now and then we have some users who would benefit significantly from a
much larger pagepool on compute nodes but by default keep it on the
smaller
