.TH COREUPDOWND 1 COREUPDOWN
.SH MAME
coreupdownd - Dynamically enable and disable CPU' to only use one during low CPU usage
.SH SYNPOSIS
coreupdownd
.SH DESCRIPTION
The
.B coreupdownd
daemon dynamically turns all CPU cores, except except
the main one, on and off depending on CPU usage.
.PP
The daemon periodically determines what the CPU usage
would be if only the main CPU core was enable. If it
would be saturated, the other cores are enabled, otherwise
the they are disabled.
.PP
This is designed as a workaround for virtual machines
that have input performance issues (keyboard input lag
and keys getting stuck) when more than one CPU core is
online.
