I'm about to run CURRENT on a rather modern laptop with all the
fancy power-control stuff, which I've never done before, so this
thread is rather interesting to me.  According to rc.conf(5),
performance_cx_lowest specifies a CPU power state when idle.
Shouldn't it have no effect on the CPU speed when it has some real
work to do?  Looks like there is significant latency in the CPU's
transition from idle state to active state -- at least in your case.
