[Openstack] Cinder iscsi performance

Hello All, 

Fighting an issue with cinder iscsi performance being much slow than local ephemeral disk.  We’re running multi-path with dual 10Gb nic, offloading is working and bandwidth across the links is minimal.   I’ve looked at kernel schedulers in the VM’s and tried them all.  

I still need to dig into the storage side (3Par), but just curious if anyone has any suggestions while I keep troubleshooting.  

Thanks for any help.

JC
