This seems like a major regression for using ZFS over UFS. The idea that this might be happening has caused me to regard my ZFS store as a largely nfs/smb appliance. Certainly it does well in this role --- and dedicating a system to many terrabytes of store isn't the end-of-the-world, but having used ZFS on my laptop --- and all the pain that incurs --- I'm shy about using ZFS on anything that isn't essentially a disk appliance. ZFS should be better than that. If the cache/VM aren't integrated on FreeBSD, are they integrated in OpenSolaris?
