Speed up composer!

Are you experiencing slow composer update? Well there is a solution!

After some google research I have found to Fixes!

Let’s start with some benchmarks

Benchmarks – Small Json

Before every test I have executed composer cache:clear so the results don’t cheat by using the cache!

I have just this Test composer

    "name": "mrlewis/test",
    "description": "Composer test",
    "type": "project",
    "require": {
        "monolog/monolog": "^1.23",
        "doctrine/instantiator": "^1.1",
        "symfony/console": "^4.0",
        "symfony/debug": "^4.0",
        "doctrine/annotations": "^1.6",
        "doctrine/dbal": "^2.7",

That’s a big difference!!!!

Fix 1

Yeah this is the part were you all have been waiting for!

Change the IP which you use for packagist.org I use this one now and it is very fast!

Just add the following line to your /etc/hosts (when you have MacOS) packagist.org

More information about this you can find in this old article in which the IPs are no longer the same

Fix 2

Start using prestissimo a composer plugin. This is a composer plugin that downloads packages in parallel to speed up the installation process.

Easy to install by running composer global require hirak/prestissimo
