The mean speedup for SMP in 2.2 deals with locking.  Specifically,
certain parts of any kernel must not be run simultaneously.  2.0 had a 
lock for the entire kernel; the locking in 2.2 is much more
fine-grained.  This will not impact things that do pure computation or 
require few kernel services, but for things like network servers that
use lots of kernel services, it can be important.
