We have started to extend musl with optimized routines like glibc does. But really, the performance difference is usually minimal.

Is this something that you are planning to upstream? Or will it be local to Alpine?

That activity is being driven in musl directly. 1.2 has introduced optimizations for arm, aarch64, x86 and x86_64. there's more to optimize, but some are already there.
