Ross,
Actually, we just had a reason to care. We just changed from raid 5 to raid
1+0, and wanted to determine how and where we achieved performance increase. We
weren't interested in knowing how we compared to a museum machine, but in how
we compared to the weekend before. We did see quite a p

"X" was a benchmark available at the time. I am not certain, but I
think it was written and published by Ultimate. Assuming my memory is
correct on that, a 2X ADDS machine would be one that ran the Ultimate
benchmark twice as fast as the original Ultimate machine did.

Dear Dawn et al.
From reading other posts on this matter about UV/UD scaling, I expect that
as far as the PRDBMS and hardware, the sky is the limit. And with Claus
Derlien's comment about 3 users at France Telecom, the sky is pretty
high up there.
But I wonder about the applications. I k
