I think you are seeing ZFS store up the writes, coalesce them, then flush to disk every 30 seconds.
Unless the writes are synchronous, the ZIL won't be used, but the writes will be cached instead, then flushed. If you think about it, this is far more sane than flushing to disk every time the write() system call is used. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
