  2. Re: Performance at read time

    Sorry, but are you talking about read policies or something else?

    On read policy see vxintro man page, search for "read policy". 3 policies, preffered plex, round-robin, and select.

    If you are talking about layouts and how different layouts differ or how they affect performance then you can read vxvm admin guide, it will have some on this...
