prestissimo

This is a composer 1.x plugin that downloads packages in parallel to speed up the installation process. This plugin is for Composer1; Composer2 is very fast on its own. Recognize composer's options. You don't need to set any special configuration. To avoid Composer asking for authentication it is recommended to follow the procedure on composer's authentication. For github.com you could also use an auth.json file with an oauth access token placed on the the same level as your composer.json file.
