Hi Tim, Sorry for mailing you directly; I meant to reply to the list. My mistake.

The graphs are pretty informative, even so. You can see the limitations of raid-z on it pretty clearly - 200 megabytes per second requires six thousand IO/sec?! That's about 30k per I/O, which lines up with what's expected for 128k stripes on five-wide stripes... but that's still a lot of overhead.

Having local equivalents to the samba tests would also be interesting - write a local file at maximum speed, and see how fast that goes and how many I/Os that generates. for example. Non-sequential tests would be neat, too.
