[ceph-users] Ceph iSCSI Performance

All; I've finally gotten around to setting up iSCSI gateways on my primary production cluster, and performance is terrible. We're talking 1/4 to 1/3 of our current solution. I see no evidence of network congestion on any involved network link. I see no evidence CPU or memory being a problem on any involved server (MON / OSD / gateway /client). What can I look at to tune this, preferably on the iSCSI gateways? Thank you, Dominic L. Hilsbos, MBA Director - Information Technology Perform Air International, Inc.
