Thanks for the pointer, will go out and look into the ZFS + direct I/O details. Would it be asked too much to have fio emit an error message hinting towards the "FS needs to be direct I/O aware" caveat? > > On a related note: do you guys have access to Solaris systems?

Understood. Feel free to let us know in case you find yourself in need of Solaris access anyway.
