So what about other sysctls? Is it just these sysctls? It may be the
case that these values are not simply read from some variable in the
kernel, but really performs some hardware calls. Still, 436 msec is
quite a lot of time.
===================
getting the same info on a linux box from /sys/class/power_supply/BAT0/*
takes <10ms, even when reading all 32 files in the directory.
meanwhile, on freebsd, the other hw.acpi.* variables i've tried are either
reasonably fast (2-7 mS) or as slow, but no slower. at least not the
handful that i've tried.
hw.acpi.battery.* are the ones i'm actually interested in.
