Both the in-kernel C variant and libc asm variant have very poor performance. The former compiles to a single byte comparison loop, which breaks down even for small sizes. The latter uses rep cmpsq/b which turn out to have very poor throughput and are slower than a hand-coded 32-byte comparison loop. Depending on size this is about 3-4 times faster than the current routines. Reviewed by: kib Approved by: re (gjb) Differential Revision: https://reviews.freebsd.org/D17328
