    Andrew> I get the exact opposite, on a P4:

    Interesting. I gave it a try on a couple of my UMLs. One is on a P4
    (possibly xeon; not sure) and the other is on an athlon. The p4 did
    shared about twice as fast as private and the athlon was 50% faster.
    (p4 uses uml kernel 2.4.27; athlon 2.6.6; no idea what the hosts run.)
