While the performance difference may not be significant,
the energy difference may be.
Some people think it is serious when Linux has worse out-of-box
energy efficiency than Windows on the same hardware.
Some people think that it is serious when their Linux distribution
has worse energy efficiency than competing Linux distributions.
Greg has given me a hard time for not cc'ing stable _enough_.
I guess the folks that answer the stable mail get to decide...
cheers,
