Hello,

What kind of x86 CPU does ZFS prefer?  In particular, what kind of CPU is 
optimal when using RAID-Z with a large number of disks (8)?

My experience is that for hardware that will be used in a
server orientated role, there are a lot of considerations
that need to be taken into account in addition to MHz and
cache sizes.

But for ZFS, it has been said often that it currently performs
much better with a 64bit address space, such as that with
Opterons and other AMD64 CPUs.  I think this would play a
bigger part in a ZFS server performing well than just MHZ
and cache size.
