Compile frequently-used classes

[thewilkybarkid]

To try and reduce the amount of classes that are autoloaded, I've tried to work out which Puli classes are frequently used in production and add them to the compiled list.

I imagine that this list isn't completely optimised (eg some missing).

Given that this makes debugging harder and that nowadays Opcache alone should be sufficient is this really something worth to do?

Good question. Any benchmarks on a recent PHP version with an opcache?

@javiereguiluz did some benchmarks for EasyAdminBundle (see javiereguiluz/EasyAdminBundle#1003). Not sure if that's helpful for you though.

In our case the gains were minimal. Be careful because the classes to compile can't contain neither annotations nor __DIR__ or __FILE__ constants, as @stof reminded me today while reviewing symfony/symfony-docs#6405.

Thanks for the feedback @javiereguiluz. I guess we can close this then.
