It works much better for me now. I can now play with sysctl hw.setperf
without freezing the system.

The first time I touch hw.setperf, I'm getting the follewing response:

        # sysctl hw.setperf
        hw.setperf=100
        # sysctl hw.setperf=0
        sysctl: hw.setperf: Operation not permitted

The secound time I get this response:

        #sysctl hw.setperf=0
        hw.setperf: 0 -> 0

and the system becomes slower and cooler.

md5 -t, time before: Time   = 0.494368 seconds
md5 -t, time after:  Time   = 0.890196 seconds

Even though I get the expected response,
      #sysctl hw.setperf=100
      hw.setperf: 0 -> 100
when I try to change back to full speed, the system continues to run
"slowly and cool".


Btw. should these reports be kept offlist, and if so, whom should I
mail, tedu@ or Gordon Klok ?
