my son read somewhere that linux does better power management than
freebsd. one specific item being that the cpu scaling is more
efficiently handled.

my friend told me that freebsd does it better ;)
anyway it's just "been told", "somewhere" etc.

to compare things we first need to set up a metric :)

i don't know much about this stuff so i thought i'd ask here.

1. is there any accuracy to the statement?

2. is cpu scaling a kernel issue? if so, does this mean that the linux
kernel has coding in it which deals with the scaling better?

IMHO it depends on hardware and ACPI. maybe linux handles strange cases better maybe not.

Simply - install linux, then FreeBSD on same machine and check it :)
