Experimental results for candidate Boost Bloom Library

The tables show the false positive rate (FPR) and execution times in nanoseconds per operation for several configurations of boost::bloom::filter<int, ...> where N elements have been inserted. Filters are constructed with a capacity c*N (bits), so c is the number of bits used per element. For each combination of c and a given filter configuration, we have selected the optimum value of K (that yielding the minimum FPR). Standard release-mode settings are used; AVX2 is indicated for Visual Studio builds (/arch:AVX2) and 64-bit GCC/Clang builds (-mavx2), which causes fast_multiblock32 and fast_multiblock64 to use their AVX2 variant.

For reference, we provide also insertion, successful lookup and unsuccessful lookup times for a boost::unordered_flat_set<int> with the same number of elements N.
