Most of http://wiki.freebsd.org/ZFSTuningGuide
is for i386 and amd64.
I'm using zfs on ia64 r238540.
Not sure how much of the advice given apply in my case.
I have:
# grep ZFS /var/run/dmesg.boot
ZFS filesystem version: 5
ZFS storage pool version: features support (5000)
# zpool upgrade -v |tail
23 Slim ZIL
24 System attributes
25 Improved scrub stats
26 Improved snapshot deletion performance
27 Improved snapshot creation performance
28 Multiple vdev replacements
For more information on a particular version, including supported releases,
see the ZFS Administration Guide.

Do the vm.kmem tunables look reasonable?
Thanks
