the second choice.

You can see how things are balanced right now, in terms of both size
used on each vdev and io/s on each device, using 'zpool iostat <pool>
1'.  the interval timing seems kind of goofy though---when the pool is
busy the intervals are longer than one second, which sort of defeats
the purpose of bucketing, so it is just a rough-guess kind of tool,
not the serious statistics collector it looks like.
