Interesting performance increase! I'm Iscsi it at a few installations and now a wonder what version of Centos is required to improve performance! Did the cluster go from Luminous to Mimic?

I have not experienced any hick-up since the upgrade. You will always have a degree of performance hit when using the iGW, because it's both an extra layer between consumer and hardware, and a potential choke- point, just like any "traditional" iSCSI based SAN solution. If you are considering to deploy the iGW on the upstream bits then I would recommend you to stick to CentOS, since a lot of it's development have happened on the RHEL platform.
