The whole reason your Apache was (kind of) expensive to fork was PHP. You've only moved that forking to the PHP-FPM process.
But that said, forking processes is not really a problem unless you do really long lived connections (such as longpoll handlers). Many other languages do that. Not many other languages have kept the CGI-like request model that PHP has, though.
It encourages things like parsing code or even opening database connections on every request, unless you cache them. (Which you probably do if you are a PHP developer. But it's not always as automatic as one would hope. Have you checked your application still fits in the cache you set up?)
