Subject: how many cores does the leopard line really need?

So here's some thinking, don't be shocked.

So far as I understand, we have been looking only at 8-core systems for
leopard.  The question is, how many do we really need?  A 4-core
seemingly should be quite capable of doing what we need.  I'd certainly
be surprised if a 1.8GHz 8-core didn't easily handle the performance
tarkets we are aiming for with the first and second releases of this
product line.

I think we should do some tests in this area so that we can determine
which would be the best approach, COGS wise, ala high speed 4-core v.
lower speed 8-core or do we really need a medium to high speed 8-core?
A lower speed 8-core might turn out to be the most cost effective,
depending on the multithreaded-ness ZFS.

Comments?

Cheers,
