Finding the fastest mirror

After you install Alpine, you may be wondering how do I figure out the fastest mirror again?

Contents of /home/user/fastestmirror

data=""
for s in $(wget -qO- http://rsync.alpinelinux.org/alpine/MIRRORS.txt); do
        t=$(time -f "%E" wget -q $s/MIRRORS.txt -O /dev/null 2>&1)
        echo "$s was $t"
        data="$data$t $s\n"
done

echo "===RESULTS==="

echo -e $data | sort
