I'd think that for pure sequential loads, larger column setups wouldn't have too many performance issues. But as soon as you try to do random reads on the large setup you're going to be much more limited. Do you have tools to do random I/O exercises? -- Darren _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
