PSALLOC and paging space allocation mode
From Wikistix
AIX uses the PSALLOC environment variable to control paging space allocation mode. The two available modes are:
- deferred, otherwise known as lazy (default). Any value other than early will result in this mode.
- early, otherwise known as reserved.
This is mostly equivalent to the linux sysctl knob, vm.overcommit_memory, described in overcommit-accounting.
