I don't know what you're saying, but I'm quite sure I disagree with it. Regardless of multithreading, multiprocessing, it's absolutely possible to have contiguous files, and/or file fragmentation. That's not a characteristic which depends on the threading model. Also regardless of raid, it's possible to have contiguous or fragmented files. The same concept applies to multiple disks. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
