Yes. But we're specifically talking about sync mode writes. Not async, and not read. And we're not comparing apples to oranges etc, not measuring an actual number of IOPS, because of aggregation etc. But I don't think that's what you were asking. I don't think you are trying to quantify the number of IOPS. I think you're trying to confirm the qualitative characteristic, "If I have N slogs, I will write N times faster than a single slog." And that's a simple answer. Yes. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
