The dynamic tick patchThe dynamic tick patchPosted Jun 16, 2005 9:33 UTC (Thu) by farnz (guest, #17727)In reply to: The dynamic tick patch by jg Parent article: The dynamic tick patch Also, most CPUs take a long time to switch from run to sleep; at 1kHz tick, there's a good chance that the "sleeping" CPU is actually running for a decent stretch of time. As they can switch back almost instantly, a good power saving technique is to try and maximise the time between a "go to sleep" command, and the next wakeup, which is exactly what dynamic ticks does.
