Hi, As per feedback given here: https://lists.boost.org/Archives/boost//2025/05/259548.php I've experimented with the hash production scheme suggested by Kostas, where h_{i+1} is calculated as h_i * 6364136223846793005 mod 2^64: https://github.com/joaquintides/bloom/blob/refs/heads/feature/alternative-ha... These benchmarks show the performance of each filter configuration with the original mechanism and, on the next row, the new mechanism (filter names marked with *): https://github.com/joaquintides/boost_bloom_benchmarks/blob/alternative-hash... I can't draw any definitive conclusion as to whether the new mechanism affects performance, probably because the GHA-run benchmarks have a good deal of noise and variations in CPU speed. Maybe a keener eye than mine can tell, or if you're interested in trying the benchmark locally please tell me so and I can instruct you on how to do it. Feedback welcome, Joaquin M Lopez Munoz
