It might but they're not externally visible except from a RAM utilization
standpoint. ZFS will eat a lot of RAM in certain situations.

I have Solaris running on SPARC hardware for development and on x86 as in
internal web and application server and I've been using ZFS on Solaris from
back in the Sun days.

ZFS has great management features. You have a very fine level of control of
attributes at the pool and file system level. You can change things like
the kinds of compression and checksum used per filesystem, whether it's
r/w or r/o, etc. all on the fly. You can export an NFS mount with one
command, /etc/exports is no longer needed. Much to be said here.

You need server grade hardware though. ZFS expects all the devices to work
and doesn't get along real well when they don't although this has improved.
