This maybe is not a problem with comstar.I test smb ,the result just like above result.

If your using HW raid try going direct to disk or using soft partitions instead of ZFS and see how the performance is there.

That should be the best you will get and adding ZFS will mix the results depending on block or record size.

I find either the drivers or io scheduler in Solaris leaves something to be desired and doesn't drive HW RAID to it's potential.

It's a shame really because the OS is nice to work with.

Local services should benefit from ZFS though, just remote storage suffers.

If anybody has any suggestions on how to improve/tune HW RAID or IO scheduling I'm all ears.
