non-RAC -- 112036 or 112037 -- Linux x86-64 (RHEL6)

High latencies with a ZFS file system and dNFS.
3000+ ms latency in the InfiniBands (IB)
These servers have both IB and 10gE interfaces.  The 10gE are also connected to NFS servers (just not ZFS/dNFS capable)
The servers do not have 10gE to the ZFS.  It has been tried the ZFS via 1gE and works (ie, no latency spikes) but 40x slower.

Checked but still no solution:
