Thanks for the explanation, Matan.

There is a very noticeable improvement in speed when running CPU-intensive applications, so the CPU must be throttling down even when there are tasks running. It would be nice if there were a setting between "performance" (always full speed) and "on-demand" (throttling at first opportunity).

Even if there is some impact on battery life, turning off the CPU throttle is a "cheap" and "easy" way to get some more speed for demanding tasks.

Certainly easier than putting in a new CPU or trying to "overclock" it.
