Are they so afraid they have to write such bullshit!?

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

Does this mean it would be a good practice to say increase the amount of
memory and/or swap space we usually recommend if the customer intends to
use ZFS very heavily?
Sorry if this is a dumb question!
Warmest Regards

ZFS doesn't necessarily use more memory (physical or virtual) than UFS
it needs more VM *address

Memory is always good; but it is *virtual* memory (address space) which
matters most.
The 32 bit kernel only has a

Indeed. There was a followup to that email that went
through and debunked that posting along exactly those
lines and to which the OP did not respond.

offtopic query :
How can ZFS require more VM address space but not more VM ?
The real problem is VA fragmentation, not consumption. Over time, ZFS's
heavy use of the VM system causes the address space to become
fragmented.
with ZFS the primary driver isn't cpu, its how many drives can
one attach :-) I use a 8 sata and 2 pata port

H8DCE can't use the SATA HBA Framework which only

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.
