There is a package to speed up your composer. It may be useful

1. Disable Xdebug Turn it off and be happy.

2. Use Prestissimo is a global Composer plugin that installs dependencies in parallel. It is crazy fast. It’s worth noting that Prestissimo requires cURL, which may not work behind certain firewalls or proxies. I haven’t run into any issues at all personally.

Try hirak/prestissimo Composer plug-in. It will drastically reduce dependency installation process of any large project.
