hello, I'm upgrading my site and I have some question on memory. I try to use Doctrine, models, and all this stuff. By making some benchmark I noticed that a single request can take 4Mo of memory. Is that huge? Or is that acceptable in face of the beneficts of a good architecture ? I read that the default configuration allow 128Mo so 4Mo can seem ridiculous, but I am not sure. So if you can give me your feeling. Thank you
