We are currently in the process of moving to iSCSI with our OpenNebula + Nexenta deployments, and are expecting a boost in performance as it relates to the initial deployment of VMs.
Do *NOT* use iSCSI on Nexenta.

We used it in the past and run into different problems. F.e. it caused:
a complete freeze/panic of nexenta, reaching connection limit and
blocking until reboot of nexenta.

Maybe your problem is not related to NFS.

Do you use ZFS dedup or did you use ZFS dedup in the past?

Did you move your ZIL to SSD?

How old are this SSD?
