Research direction
Start by locating the Skein implementation and its skein/512-rust benchmark, then compare its measurements with the skein/512-sphlib reference shown in the issue. Done means the Rust implementation's benchmark performance is substantially improved and the benchmark results document the change.
Written by the indexing model from the issue text.
Description
The C implementation of Skein in https://github.com/pornin/sphlib is 5x+ faster than the one in RustCrypto/hashes.
skein/512-rust time: [1.3714 µs 1.3734 µs 1.3753 µs]
Found 6 outliers among 100 measurements (6.00%)
4 (4.00%) high mild
2 (2.00%) high severe
skein/512-sphlib time: [200.72 ns 200.79 ns 200.88 ns]
Found 8 outliers among 100 measurements (8.00%)
3 (3.00%) high mild
5 (5.00%) high severe
