Ah but to paraphrase our friends at SUN:

   The Network IS the problem

No matter how fast your system is, if your network is a standard ethernet
(or normal token ring for that matter), the bottle neck will be the network
and not your system. 

Also are the DN10000's disks fast? I don't think they are compared to some
of the new technologies coming out. Are their any plans out their in HP
land to speed up the disks on the 10000?

Cheers,
Alan
