Make that _reality_. In some tests I've done with FTP, I have seen
*significant* improvements using dual and quad processors using 2.4. Under
2.2, there are improvements, but not astonishing ones.

Things like 90% saturation of a Gig link using quad processors, 70% using
dual processors and 55% using a single processor under 2.4.0test. Really
amazing improvements.
