Note that the MO-IMDB scenario is challenging one given that the mappings used are relatively complex. Our algorithms still have some issues optimizing of the generated queries. We expect these numbers to improve with each release of the system, as we improve our optimisation techniques.
The following tables give you the performance values that we obtained running this scenario on an average desktop PC with 8 gb of RAM. We ran a couple of warm up queries before compiling these numbers as of January 2013.
