Yes, we had Oracle DB already installed and started test imports. Those take about 50 minutes on our old V440, and we aborted them after 3.5 hours on the T5220 LDOM. dd testing was the easiest way to show some raw numbers. Meanwhile I reconfigured the Machine to use zones instead. Disk speeds are good. Oracle runs well in a seperate ressource pool. But while creating all the datafiles I saw the global zone was under a load of 7.5 constantly. I had the control domain set up with only 4 vcpus. Maybe that was the bottleneck actually? Could it be that for ZFS backend one should assign at least 8 vcpus to the control domain?
