The pagezero daemon is a performance enhancement that reduces the elapsed time for completing kernel operations like page faults, mlock(), and so on. The idea is to zero out large free pages (4MB and above in size) during times when the CPU is idle. The daemon has been specially designed to ensure that it only executes for brief times when the CPU is idle.
