Why updating of dependencies in composer is so slow?

Question

I am using composer (http://getcomposer.org/) to manage installed bundles in the Symfony2 (symfony v 2.1.3). Version of the composer is de3188c.

Answer 1

To diagnose this use I used the require command with -vvv attribute.

composer require larapack/dd -vvv

In my case I've found that the slow speed of composer was because of fxp/composer-asset-plugin.

composer global show
composer global remove fxp/composer-asset-plugin

and voila
