First, please don't hijack threads. Opening a new thread is far more
useful.

As for your question, your machine is most likely dynamically
down-clocking the CPU in-order to reduce power usage. (In AMD's case,
it's called Cool&Quiet)
Once the CPU load increases, the CPU speed will increase.

Try this, open console, and type:
$ while [ 1 ] ; do echo -n ; done & sleep 10s; cat /proc/cpuinfo | grep MHz ; kill %1

You should see the CPU speed increase.
