>Your notion that forked = better is outdated.

You're beating a strawman here. Nowhere did I make the claim that it was better. I even said multithreading is more performant. The only claim I make is that immutable and shared nothing model of PHP servers makes horizontal scalling more straightforward.

>You're going to be using a thread pooled server anyway to handle requests

That doesn't take away the fact that n parallel requests will require n threads.

>And this doesn't even get into the more efficient compilation. PHP has no JIT yet. There's overhead for type inference. Etc etc

I don't make any claims here either. Of course Java is faster here. My point was specifically about which model of concurrency and paralellism is better for server IO.
