It is however in production use in several projects. I would urge you to make create issues on the GitHub project if you're missing functionality, but I cannot promise to actually implement it :-) About performance: the plugin does not really perform queries itself, it just makes it easier to write complex OLAP queries. So, beside some constant overhead to build the SQL query and interpret the result, the performance is dependent only on the database work. The heavy lifting is done by your database. So, wise database design and setting the appropriate indices is a must to get decent performance. At Floorplanner, we use this plugin to query our data of 1+ million users on the live database and it performs fine. Of course, you can always create a separate database with customized indices for reporting only to get improved performance.

And I can't find any words about performance. OLAP assumes that all queries should be very fast. Have u tested on big data amounts? Actually the idea is great. Thnx! Hi!
