I don't believe you understand the role of the ZIL. I see no correlation between the ZIL work and the other ZFS use of the vdevs. I also don't see many workloads which a laptop user would run which would use the ZIL. The two main workloads are databases and NFS service, neither of which are commonly used on laptops. I do believe that ZFS will be much better for CFs than UFS, particularly if you actually install to the CF (rather than copy an existing installation). If you get a chance to try it, please let us know how it works for you. -- richard This message posted from opensolaris.org
