[Rails] Too big classes

Hello Folks, Have a doubt. I am in a project where Model gets bigger and bigger. Yes we are breaking up into concerns, but what we are not sure of is weather this code will get included in RAM when we call say b = Book.new or something, thus making the Rails app occupy more memory. The most bulk

Re: [Rails] Too big classes

AFAIK , On production mode, rails has a default configuration called "eager_load" ( config.eager_load ) . This loads all the classes into the RAM for faster access( cache ) . But for b1 = Book.new, b2 = Book.new , The class and methods are not loaded twice. The object is created and occupies RAM.
