+
+The project to enhance the libc with SIMD implementations of string functions for amd64 has now concluded.
+In total, SIMD implementations for 17 libc functions have been written, complemented by scalar implementations where needed.
+Through this rewrite, performance of these functions on strings with an average length of 64 characters was improved by an average factor of 5.54.
+In addition, 9 other library functions were rewritten to call into the SIMD-enhanced routines, conveying benefits without requiring additional assembly implementations.
+Please see the FreeBSD Foundation blog post linked above for more details.
+
+Parts of the SIMD work are already found in the CURRENT branch.
+The rest is currently undergoing acceptance testing and will be merged if no problems emerge.
+It is planned to back port all improvements to 14-STABLE for inclusion into FreeBSD 14.1.
