Of course there''s always something that doesn''t really get addressed when you take a spreadsheet or bullet point approach. Or you could take the microbenchmark approach with something like Richard''s filebench project: http://opensolaris.org/os/community/performance/filebench/ IMO the latter is more of a step in the right direction but the problem sets may be very different depending on your applications - it can be a tough decision to determine which numbers matter the most when you have to make tradeoffs .. your best approach is typically to try and decide some form of CTQs for your applications or organizations that take into account the relevant factors (administration, volume management, storage platforms, performance, recovery, operating systems, etc) and match up features and performance considerations concurrently. I think you''ll find that ZFS is an amazing fit for most applications, but in cases where you may think you need directio or non-buffered sorts of behaviour .. you could be at a slight disadvantage. Of course Sun also offer QFS as another high performance alternative .. but like the old mantra we''ve all heard too many times now .. (everyone together) .. "It all depends on what you''re trying to do" .. --- .je (* disappears back into the mist *)

The free-license restrictions are targeted towards small systems. They are also pricing support by number of CPUs, how 20th century! ZFS has no such restrictions.> I wonder if ZFS has "helped" it to happen :)I''ll give them some credit, it is a step forward. -- richard
