All I can see it that it's running busybox and a two year old kernel.
I would have gone for a simpler loop:
echo -e "sec\tmethod\turl";for url in {https,http}://{www.,}{en.wikipedia.org,{google,reddit,facebook,youtube,netflix,amazon,twitter,linkedin,msn}.com,google.co.in}; do curl -sL "$url" -w "%{time_redirect}\t${url%:}\t${url#//}\n" -o/dev/null; done|sort
Try this: curl -sL https://{www.,}reddit.com -o\ /dev/null{,\ } -w "%{time_redirect}\n"
