I see also that Lindsay told you small ceph setups don't give good performance; don't know about his experience, but mine is quite good. We have 4 3-node clusters (with 3-10 VMs) with ceph and are very happy with the performance. It is very important to choose the right SSD for the journal.
Yah, enterpise grade SSD is essential, and very expensive. Also Jeremy only has one disk per node, which just won't provide enough IOPS for ceph.
Do you have barriers enabled for your ceph osd filesystem? my performance was ok until I (as recommended) did that.
