Wouldn't it make sense for the timing technique to be used if the data is coming in at a rate slower than the underlying disk storage?
But then if the data starts to come at a faster rate, ZFS needs to start streaming to disk as quickly as it can, and instead of re-ordering writes in blocks, it should just do the best it can with whatever is currently in memory. And when that mode activates, inbound data should be throttled to match the current throughput to disk. That preserves the efficient write ordering that ZFS was originally designed for, but means a more graceful degradation under load, with the system tending towards a steady state of throughput that matches what you would expect from other filesystems on those physical disks. Of course, I have no idea how difficult this is technically. But the idea seems reasonable to me. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
