Java is a compiled language. PHP is not. If you need to do a benchmark to realize that a compiled language is faster than its dynamic counterpart, then I really don't know what else to say to you.
Some compiled languages are faster, some aren't. Speed of execution is largely related to the optimizations the interpreter / compiler can do, and in many practical cases the qualities of the default library. The other problem is that many interpreted languages are implemented in C leading to the usual performance implications of inner-platform effect. Another problem is the underlying CPU architecture, the vast majority of CPUs are designed to execute C-like languages.
What is your point? That does not chance the fact that using Php for a huge site like Facebook is a poor choice. A very poor choice indeed. They must be wasting energy on hundreds of servers because of this choice. One can hope that they are using Php only for the very basic front-end operations otherwise they are royaly screwed.
I don't know why you are saying anything to me since you are responding to something I didn't say and that has nothing to do with the post I made. Is "dim witted attempts to respond to poorly thought out strawmen" really the level of discourse here?
You. You may want to consider that if there's two replies to your post, and both are "your post is entirely irrelevant", then perhaps your post genuinely is entirely irrelevant. Protip: read the whole thread from the top.
Where did I say "dim witted attempts to respond to poorly thought out strawmen" or "your post is entirely irrelevant"? Either you're confusing me with someone else or you don't understand the concept of quotes.
Again, read the entire thread. I am not confusing you with anyone else, and I understand the concept of quotes. You are failing to grasp the context of posts, and assuming everything anyone puts in quotes must be a statement you made. There are other people who post, why on earth would you think "your post is entirely irrelevant" is something I claim you said? I very clearly pointed out that two people replied to you saying that your post is irrelevant.
Clearly that is not a situation I can remedy for you. I suggested you read the thread, as that would resolve the confusion for anyone with basic reading comprehension skills. If that is not sufficient for you, then you'll need to ask an adult to explain the words you don't understand.
