No, actually under Ubuntu, in the case at hand, it was running one processor at full 1.6 GHz
and the other idle at .8 GHz; Windows XP was running both at 1.6 GHz, presumably one at fast idle.

For the same computation (Cygwin under XP), taking the same amount of time (ten minutes).

Vast quantities of superhot air was blowing out under Ubuntu; nothing noticeable under XP.

(There's a laptop cooler under the thing, so air moves regardless what the system wants.)

So I think fan management is probably something to look at. It can differ over systems, and if the
hardware is newer than Ubuntu, it might be doing the wrong thing.
