I cannot find any information on using the new php 7.4 preloading feature with Heroku. Since we need to input a path, I'm not sure if I can do it manually
For example in Symfony this can normally be enabled with a simple one-liner in the php.ini: https://symfony.com/doc/current/performance.html#use-the-opcache-class-preloading
It's supposed to add about 75% performance. That's quite a lot, so I'd like to use it - and I'm probably not the only one :)
