I have a question as a relatively novice PHP developper. Let's say you have this Intranet web application, that deals with the generation of file bundles that could become quite large (let say in the 800 MB) after some kind of selection process. It should be available to many users on this Intranet, but shouldn't require any installation. Would it be a case where optimizing for microseconds would be recommended? Or would PHP not be the language of choice?
