zfs discuss - Jan 2011 - How to increase iometer reading?

Hello,

We are building a zfs-based storage system with generic but high-quality
components. We would like to test the new system under various loads. If we find
that the iometer reading has started to reduce under certain loads, I am
wondering what performance counters we should look for to identify the
bottlenecks. Don''t want to replace a component just to find that there
was no improvement in iometer reading.

Thank you in advance for your insight.

Regards,
Peter

fsstat zfs 1
zpool iostat 1

any suggestions beyond that will require a lot more detail on your
setup and target workload
