I did with pkgsrc and compared the relation of cpu frequency
(2.2GHz / 800MHz) with compile speed (-j4 on dual core) and
cpu temperature.

The results are as expected:

high cpu frequency is high compile speed and
high cpu temperature (60-70 C degree)
low cpu frequency is low compile speed and
low cpu temperature (50 C degree)

both cpus idle results in about 40 C degree cpu temperature
