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

mkdir ~/.tmp
wget -q -O ~/.tmp/MIRRORS.txt http://rsync.alpinelinux.org/alpine/MIRRORS.txt
L=$(cat /tmp/MIRRORS.txt)

data=""
for s in $L; do
        t=$(time -f "%E" wget -q $s/MIRRORS.txt -O ~/.tmp/MIRRORS.txt 2>&1)
        echo "$s was $t"
        data="$data$t $s\n"
done

echo "===RESULTS==="

echo -e $data | sort
