This library counts the letters ACGT as fast as possible.
On 72 logical cores we achieve a throughput of 80.19 GiB/s.
On a laptop with 8 logical cores we obtain 13.766 GiB/s.
rust
use genome_counter;
let results = genome_counter::count_opt(b"ACGT").unwrap();
assert_eq!(results.a, 1);
assert_eq!(results.c, 1);
assert_eq!(results.g, 1);
assert_eq!(results.t, 1);
We use critereon.rs for benchmarking which yields the following results on 100e6 bytes:
