We had a "bug" in our previous benchmark ("mspw_bench.sql"). The way it was written allowed SQLite to short-circuit column data retrieval, ending up with minimal exercising of the CFFI layer.
I thought it was a feature :)
The attached query exercises CFFI as it should. We also checked its profiling characteristics, and it is a lot closer to what we are seen with our working query loads.
Below are timings when running it from inside mterm (so there is no import overhead):
CPython + APSW: 0 sec 956 msec pypy + APSW: 8 sec 673 msec pypy + MSPW: 2 sec 550 msec
