This daemon dynamically sets the CPU-frequency on SpeedStep-, PowerNow-, and ACPI P-States enabled CPUs depending on current cpu-utilization. It supports NetBSD 3.0 or later and DragonFly BSD.
estd is written by Ove Soerensen with patches from Stephen M. Rumble and myself. 2009 I have taken over maintainership of the estd project.
estd is also available in pkgsrc.
