That's an interesting slide, but without knowledge of the size of the dataset it could be misleading (especially considering communication costs between nodes in a cluster).
Hi infinite8s, to get additional information on how that chart was made, you can to go https://www.mapd.com/product/ scroll down to the bar chart, and click “See Details” under the chart. Shows the machines used, queries, and the source data set and size. Note that the machine configurations used to generate the chart were normalized for equivalent cost on AWS, i.e. the chart is hardware-dollar normalized.
