I have a *REALLY* hard time believing that number, because for every read/write you potentially do byte-swapping. Earlier attempts at such a thing at I believe Univ. of Utah were on the order of 10-15% if I remember right. (Which I might not be.) Also, it requires you to redo all your FS's in order to take advantage of it, which therefore makes it of little use to 99% of the poeple, and it could potentially 'kill' someone if they add it to their kernel.
