Changes since 0.1.2: - All x86 implementations include _mm_prefetch optimizations. These improve performance for very large inputs. - The C implementation performs parallel parent hashing, matching the performance of the single-threaded Rust implementation. - b3sum supports --no-mmap.

# A performance note for the "rayon" feature: Multi-threading can have
|
|
# significant overhead for small inputs, particularly on x86 where individual
|
|
# cores are very fast. On the other hand, on slower platforms like ARM,
|
|
# multi-threading can be beneficial for all inputs. There's no one input size
|
|
# threshold that would work well everywhere, and this crate doesn't try to be
|
|
# clever. If you're going to enable the "rayon" feature, you should benchmark
|
|
# it for your specific use case.
