Power Management

You may also want to enable apmd to save power if your hardware supports it. It will scale the CPU down during idle times and turn it up when the load reaches a certain point. Check the man page for a few different options.

# echo 'apmd_flags="-A"' >> /etc/rc.conf.local
# /etc/rc.d/apmd start

You can check what level (with 0 being the lowest, 100 being the highest) the CPU is running at with:

# sysctl hw.setperf

Try different levels and apmd settings to find the balance you're most comfortable with. Always running it on the lowest setting might limit the data throughput too much, but it will really depend on what hardware you're using.
