"composer update" benchmark

composer update is ...

1. download https://packagist.org/p/*.json phase
2. resolve dependencies phase
3. download package.zip phase

In Asia(Japan, China, etc), far from packagist.org(French?), RTT is terrible. So it spends long time for "1. download meta.json phase". This is the benchmark for it. I think packagist.org should use CDN like CloudFlare.
