Note that the measurements in the paper were made before they fixed a bug where they confused bits and bytes. So SQLite only used 1/8 of the reserved bloom filter space, thus increasing the false positive rate significantly:

I found and reported the bug because I wanted to know how the bloom filters work in SQLite for my uni seminar paper. Still wondering if one can find those kind of bugs with test cases.
