Hi,
I wanted to use the new performance throttling system but I had to look
for what to change so if I can prevent others from doing it. Feel free
to modify the wording :)
Cheers,
Daniel

+<h3>2014/10/23 - Performance throttling in the kernel</h3>
+Perfomance throttling is now available from the kernel. It replaces
+apmd's -C flag which has been removed. If you used this flag, remove it
+from your /etc/rc.conf.local.
+To use the new performance throttling system, set the sysctl
+hw.perfpolicy to "auto" with:
+<pre>
+ sysctl hw.perfpolicy=auto
+</pre>
+Remember to edit your /etc/sysctl.conf if you want to keep it after
+your next reboot.
