This is true. If someone wasn't utilizing 1Gbps before MC/S then going to MC/S won't give you more, as you weren't using what you had (in fact added latency in MC/S may give you less!). I am going to say that the speed improvement from 134->151a was due to OS and comstar improvements and not the MC/S. -Ross _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
