Parallel scaling. AWFM-index nucleotide Locate() search times for 1 million length 14 queries, parallelized with varying numbers of threads, from single-threaded search up to search using 32 threads against a target of 1 billion nucleotide-long target with a suffix array compression ratio of 4. a Increase in speed for the count() command, relative to single-threaded search. b Increase in speed for the locate() command, relative to single-threaded search
