These benchmarks seem strange, it looks like some sort of database test suite? And compared to the performance that is listed on the benchmarks own page[1], the Daft results look abysmal? Like Daft takes several hours to complete ten queries and the results the benchmark authors point to can do around a million queries per hour... oh, and the software they use for that is MS-SQL.
