i enabled
vm.pmap.pg_ps_enabled: 1
could you please explain what exactly this values means?
because i don't understand why promotions-demotions!=mappings
vm.pmap.pde.promotions: 2703
vm.pmap.pde.p_failures: 6290
vm.pmap.pde.mappings: 610
vm.pmap.pde.demotions: 289
other question - tried enabling it on my i386 laptop (256 megs ram),
always mappings==0, while promitions>demotions>0.
certainly there are apps that could be put on big pages, gimp editing 40MB
bitmap for example
