Well, to be fair, my computer runs hotter playing video games in Linux
than it does in XP, and it's not getting higher framerates.
Many times when it's hot in the room and XP will be just below the
threshold with the CPU fan turned all the way up, similar tasks in Linux
will require the box fan.
Obviously this is because the Linux kernel is using the processor more
intensively. As we see in the case of Windows ME burning through a wait
loop, that doesn't necessarily mean it's getting more work done.
The extra heat Linux seems to generate makes me suspect the kernel is
less efficient. It doesn't perform higher i/o or more work.
