It wouldn't hurt to check with md5 -tt and/or a power meter to see if there is actually a difference between hw.setperf=0 and hw.setperf=100.
hw.setperf=100 16.5 Watt # md5 -tt MD5 time trial. Processing 100000 10000-byte blocks...

Digest = 766a2bb5d24bddae466c572bcabca3ee Time = 4.672665 seconds Speed = 214010634.188413 bytes/second So the CPU actually gets slowed down quite heavily (apm shows 224 MHz). But the system has a greater power consumption while doing so. (Now that happens if you buy stuff in a hurry. I was aiming for a 10 Watt system. My bad!)
