Author here. I dismissed RULEs and TRIGGERs since they don't work correctly under concurrency (and most RULE-based approaches are broken even without concurrency). I felt it wasn't a fair comparison.
However, I guess it would be nice to know how much of a gain would be possible if one was willing to forfeit correct behaviour under concurrency. But that would probably require more work than I'm willing to put in, since the answer doesn't interest me that much personally at this moment.
