Your requirements could not be resolved to an installable set of packages.

Mecanisum of Composer
1. Gets /packagis.json from repository ○ Ok. It's very fast. Only 1KB.
2. Gets providers information from repository○ Gets 4 files.
3. Gets package information○ In case of Symfony Standard○ 72 files, 7.7MB○ (If there is file cache in local,
composer fetch data from here.)4. Resolve Dependencies5. Gets Package (Archive or Source)
Some ways to resolve it
● Use private repository○ satis (composer/satis を活用してComposer パッ
ケージの配布を行う http://www.bucyou.net/blog/952)○ Broker (https://github.com/researchgate/broker)
● Satis is good solution, but we need install required package in advance.
● Make mirror in Japan.
My Answer
● Better Proxy in Japan
Application
● Name: composer-proxy● Very Very simple Silex application.● Features
○ proxy and cache.
● composer-proxy.jp in Sakura-Cloud.
How to use?
● Edit your composer global configuration. (default $HOME/.composer/config.json)
{ "repositories": [ { "packagist": false }, { "type": "composer", "url": "http://composer-proxy.jp/proxy/packagist" } ]}
Speed
● resolve dependencies of symfony/console● direct to packagist.org
○ 120.24 secouns● composer-proxy.jp (cached)
○ 41.35 seconds
● 3x faster!!!
● Need more cache information in Japan!! Please use!!
In furture
● Support notice (for download count) by asyncronous message queue.
● Support search● Distribution archive cache● Add own packages
OMAKE
● vagrant-packagist (https://github.com/kawahara/vagrant-packagist)○ You can setup own packagist!○ 本当は packagist 改造しようと思ったけど、やめた残
骸。PHPer には不慣れな、solr の <del>設定もやってくれるぞ!! </del>インストールもやってくれるぞ。
