It also lists cuckoo filters to be 10 times faster than Bloom filters. In other papers, e.g. the cuckoo filter paper and the xor filter paper, the difference is _much_ smaller; maybe factor 2. https://dl.acm.org/doi/pdf/10.1145/2674005.2674994 - figures 5 and 6 https://arxiv.org/abs/1912.08258 - figures 3b and 4b&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1912.08258/"&gt;Paper and discussion history&lt;/a&gt;.
