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. # zpool list NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT tank 33.8G 148K 33.7G 0% 1.00x ONLINE - # zpool status pool: tank state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 da1 ONLINE 0 0 0 da2 ONLINE 0 0 0 errors: No known data errors # # dmesg|grep memory real memory = 6442450944 (6144 MB) avail memory = 6279823360 (5988 MB) # sysctl -a |grep vm.kmem vm.kmem_map_free: 1551581184 vm.kmem_map_size: 26427392 vm.kmem_size_scale: 4 vm.kmem_size_max: 0 vm.kmem_size_min: 0 vm.kmem_size: 1578090496 # Do the vm.kmem tunables look reasonable?
