Lower system power consumption.

The Linux kernel uses periodic timer events called “ticks” that wake up the system and bring it out of its power saving “sleep” states, causing unnecessary power consumption. SUSE® Linux Enterprise Server 11 has a “Tickless idle” feature in its kernel that eliminates periodic timer ticks when system CPUs are idle. This allows the CPU to remain in power-saving states for longer periods of time, lowering system power consumption and reducing cost. Also included in SUSE Linux Enterprise Server 11 are enhancements to eliminate unnecessary timer events, as well as improved, more granular file-based power profiles that can be more easily used by IT managers for enterprise-wide power management. These innovative power saving capabilities let you derive maximum performance per watt.
