Oh, sorry my request was not formulated clearly enough. I wanted to see
how rml performs compared to sqlite in a benchmark. Sqlite is currently 
a nice and fast solution if you do not need a remote database. Rml could 
be an even better solution, if you do not require a text sql interface,
provided that there are table types available in rml, which work without 
being fully loaded to memory.

Interesting, could you give a short overview, how it could already work.
