I think he mistyped and meant 7gbit/s. > Of course it's lower when there's significant random seeking happening... > But if you have a data model which is able to stream sequentially, the above > is certainly true. Unfortunately, this is exactly my scenario, where I want to stream large volumes of data in many concurrent threads over large datasets which have no hope of fitting in RAM or L2ARC and with generally very little locality. -- Saso _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
