Subject: Re: musl perf, 20% slower than native build?

20% is tiny measurement noise compared to the huge
variance in the environments you are comparing

try to figure out the libc api calls that are slower in
musl and why (perf can collect stats about hot paths)

(eg. if python uses regex that would explain the
difference because musl uses a slow but correct
regex algorithm unlike glibc..)
