Hello all,
I was thinking about this as I was about to put up another FreeNAS box: Would it be better to use file (ZFS) extents rather than physical ones. My reasoning behind this is that if I used file extents, I could take advantage of caching and such. I've noticed with my physical extents, I don't use any RAM as a cache (as the disk access is just a pass through). As the new machine has 32G of RAM, I would love to enable this as a cache and the only way I see to do this is through a file extent. Thoughts?
