9 worker nodes plus one master node. Each with
48GB of RAM, 3 data disks, and dual 4-core Xeon L5630
processors at 2.13GHz.
So, pretty old stuff. But note that the 100G dataset fit comfortably in RAM. If you don't fit in RAM, then the latencies are obviously going to be much worse on spinning disk. Our bet is that for OLTP workloads, you're probably going to be on flash or mostly RAM-resident these days, given the dropping prices and increasing speeds of solid-state storage.
