Hi Dean!

PH>> This machine does second-level-cache multiprocessing, doesn't it ?

It is not only as good as the used CPUs are - but I think it is also as
"good" as the used chipset and mechanisms. Second Level Cache SMP
is kind of "ugly". There should be faster methods, I think.
[Dell machine not being a totally happy SMP machine]
May be, haven't got one yet :)

DR> Also, what would you think would cause the interesting results of
the little test program?
I must have missed sth. What test program ?
