All benchmarks were performed using hyperfine with 5 runs per tool after a warm-up run.
Performance Overview
In these benchmarks, mkbrr was faster than or on par with the other torrent creation tools on each machine. On Apple Silicon, mkbrr and torf tied (9.71s and 9.78s, 1.01 ± 0.09 times). On the mechanical drives (Hetzner HDD), the run times of mkbrr varied much less than those of the other tools.Hetzner AX102
