For large files, openssl is more than 7 times faster in practice. You can also test it with the builtin benchmarks: sha256 -t openssl speed sha256 I think the reason is that openssl supports the SHA CPU extensions whereas libmd (used by sha256) does not. Any chance we can make the base sha256 faster? I guess there is some reason why we use libmd instead of openssl. https://reviews.freebsd.org/D2651 looks related but not sure it's still relevant. _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" Should probably dump sha256 anyways, blake2.help
