:to me and I will add the references and try to add to the talk.
:The talk will be 30-45 minutes long, the talk is oriented to advanced
:users and admins, we will not talk about implementation details, just
:how to use it and why to use it. Anyway, Agustin and me are interested
:in implementation ;-)
:Another thing, I was trying to measure I/O, memory and CPU for the
:benchmarking, it can do a nice compare against UFS (running in a
:similar clean DFBSD installation) but i cant find a fear way to
:compare against EXT3 or ZFS, any idea about it?
:Thanks for any help and suggestions.

    Any benchmark is going to be a benchmark of the OS as much
    as it is going to be a benchmark of the filesystem.  It's pretty
    hard to separate the two.

    ZFS is best tested on Open Solaris.  UFS is best tested on FreeBSD,
    EXT3 is best tested on Linux, and HAMMER of course is best tested on
    DragonFly.  Plus the OS itself will depend greatly on whether the
    machine environment is UP or SMP.
