Thanks all for confirmation. Since I only have a desktop, no
notebook/netbook ;-( it is somehow difficult to verify the
improvement. I now lock the cpu frequency to 1.1GHZ (half of the
original 2.1G).

Less heat means less power consumption, I guess someone suggested,
(I'm not sure that's why I asked for advise), that it takes more time
to complete the job at lower frequency so that actual power
consumption will in some case increase.
