- help
- Switches the regular HZ timer off when the system is going idle.
- This helps z/VM to detect that the Linux system is idle. VM can
- then "swap-out" this guest which reduces memory usage. It also
- reduces the overhead of idle systems.
-
- The HZ timer can be switched on/off via /proc/sys/kernel/hz_timer.
- hz_timer=0 means HZ timer is disabled. hz_timer=1 means HZ
- timer is active.
