Speed benchmarks for various compression algorithms representing approximate time in seconds to perform 100 queries across a random set of 50,000 molecules from the ChemDB (5 million similarity calculations) with Nhash = 230 using binary fingerprints and Tanimoto similarity measure. The last two lines correspond to modulo compression. Modulo-Uncorrected corresponds to computing the Tanimoto similarity directly on the compressed fingerprints as an estimate of the Tanimoto similarity on the uncompressed fingerprints. Modulo-Corrected refers to a better estimate of the Tanimoto uncompressed similarity derived in.? These benchmarks were carried on 2.0 MHz Intel-Dual Core Macintosh laptop computer.
